NZ is again being soaked this summer
NZ is again being soaked this summer

25 January 2026, 10:55 PM

For many people this summer – especially those across Northland Auckland and Coromandel – showery days and bursts of heavy rain have become all too familiar.Last week, fresh downpours on already saturated ground have again triggered flood warnings and road closures across the upper North Island.These are individual weather events, but they are unfolding against unusually warm seas that load the atmosphere with extra moisture and energy.Understanding ocean heat – and how it shapes rainfall, storms and marine heatwaves – is central to explaining what we experience on land.Looking beyond the surfaceFor decades, scientists have recognised sea surface temperatures as a key influence on weather and climate.Warmer surfaces mean more evaporation, altered winds and shifting storm tracks.But surface temperatures are only the skin of a deeper system.What ultimately governs how those sea surface temperatures persist and evolve is the ocean heat content stored through the upper layers of the ocean.A clearer global picture of that deeper heat began to emerge in the early 2000s with the deployment of profiling floats measuring temperature and salinity down to 2,000 metres worldwide.Those observations made it possible to extend ocean analyses back to 1958; before then, measurements were too sparse to provide a global view.While sea surface temperatures remain vital for day-to-day weather, ocean heat content provides the foundation for understanding climate variability and change.It determines how long warm surface conditions last and how they interact with the atmosphere above.Recent analysis by an international team, in which I was involved, show ocean heat content in 2025 reached record levels, rising about 23 zettajoules above that of 2024’s.That increase is equivalent to more than 200 times the world’s annual electricity use, or the energy to heat 28 billion Olympic pools from 20C to 100C.Ocean heat content represents the vertically integrated heat of the oceans, and because other forms of ocean energy are small, it makes up the main energy reservoir of the sea.The ocean’s huge heat capacity and mobility mean it has become the primary sink for excess heat from rising greenhouse gases.More than 90% of Earth’s energy imbalance now ends up in the ocean.For that reason, ocean heat content is the single best indicator of global warming, closely followed by global sea-level rise.This is not a passive process.Heat entering the ocean raises sea surface temperatures, which in turn influence exchanges of heat and moisture with the atmosphere and change weather systems.Because the ocean is stably stratified, mixing heat downward takes time.Warming of the top 500 metres was evident globally in the late 1970s; heat in the 500–1,000 metre layer became clear in the early 1990s, the 1,000–1,500 metre layer in the late 1990s, and the 1,500–2,000 metre layer around 2004.Globally, it takes about 25 years for surface heat to penetrate to 2,000 metres.Ocean heat content does not occur uniformly everywhere.Marine heatwaves develop, evolve and move around, contributing to impacts on local weather and marine ecosystems.Heat is moved via evaporation, condensation, rainfall and runoff.As records are broken year after year, the need to observe and assess ocean heat content has become urgent.What happens in the ocean, matters on landIt is not just record high OHC and rising sea level that matter, but the rapidly increasing extremes of weather and climate they bring.Extra heat over land increases drying and the risk of drought and wildfires, while greater evaporation loads the atmosphere with more water vapour.That moisture is caught up in weather systems, leading to stronger storms – especially tropical cyclones and atmospheric rivers, such as one that has soaked New Zealand in recent days.The same ocean warmth that fuels these storms also creates marine heatwaves at the surface.In the ocean surrounding New Zealand and beyond, these marine heatwaves are typically influenced by the El Niño–Southern Oscillation.This Pacific climate cycle alternates between El Niño, La Niña and “neutral” phases, strongly shaping New Zealand’s winds, temperatures and rainfall from year to year.During 2025, a weak La Niña, combined with record high sea surface temperatures around and east of New Zealand, has helped sustain the recent unsettled pattern.Such warm seas make atmospheric rivers and moisture-laden systems more likely to reach Aotearoa, as seen in early 2023 with the Auckland Anniversary Weekend floods and Cyclone Gabrielle.For these reasons, continued observations – gathering, processing and quality control – are essential, tested against physical constraints of mass, energy, water and sea level.Looking further ahead, the oceans matter not only for heat but also for water.Typically, about 40% of sea-level rise comes from the expansion of warming seawater; most of the rest is from melting glaciers and the Greenland and Antarctic ice sheets.Sea levels are also influenced by where rain falls.During El Niño, more rain tends to fall over the Pacific Ocean, often accompanied by dry spells or drought on land.During La Niña, more rain falls on land – as seen across parts of Southeast Asia in 2025 – and water stored temporarily in lakes and soils can slightly reduce the amount returning to the ocean.A striking example occurred in Australia in 2025, when heavy rains from May through to late in the year refilled Lake Eyre, transforming the desert saltpan into a vast inland sea.Such episodes temporarily take water out of the oceans and dampen sea-level rise.Monitoring sea-level rise through satellite altimetry is therefore an essential complement to tracking ocean heat content.Tracking both heat and water is crucial to understanding variability and long-term trends.Author: Kevin Trenberth - Distinguished Scholar, NCAR;

Hibiscus Coast Guide To Today’s Regatta
Hibiscus Coast Guide To Today’s Regatta

25 January 2026, 6:01 PM

If you are looking for a simple day out beyond the Hibiscus Coast, the Waitematā will be busy for Auckland Anniversary Day. The Auckland Anniversary Day Regatta is back today. It marks 186 years since the first event in 1840. It’s free to watch from the waterfront, beaches and headlands.Racing runs across the region through the day. A new Sail Past leaves Westhaven at 12pm for North Head.Boats of all kinds can join in, whether they are racing or not. Three NZ Warbirds Harvards are due to fly over the harbour at the same time. On the water you’ll see everything from dinghies and keelboats to classic yachts, launches, waka ama, dragon boats and radio-controlled yachts. Dragon boat racing is the biggest it has been, with more than 40 local teams and four visiting crews from China. That takes it to over 500 paddlers, racing throughout the day in the Viaduct Harbour for close-up viewing. The tugboat race also marks 20 years since it was added in 2007, and it remains a crowd favourite in the central harbour.Youth sailing is again in focus at Kohimarama Yacht Club, with the Optimist and Starling Auckland Championships incorporating the regatta and bringing hundreds of young sailors onto the water. Competitors can round the day off at a new After Party at the Royal New Zealand Yacht Squadron, with live entertainment from the Royal New Zealand Navy Band. It’s a nice family day out in the City of Sails. From the Hibiscus Coast, you can head in for a look, get a feel for the boats in motion, and head home once you’ve had your fill.Know something local worth sharing?Send it to [email protected]

Auckland Opens Waste Rules Consultation
Auckland Opens Waste Rules Consultation

24 January 2026, 7:25 PM

Hibiscus Coast locals can have their say on proposed Auckland waste rule changes, with consultation open until 11.59pm on Sunday, February 22, 2026.Auckland Council is consulting on updates to its Waste Bylaw and associated controls.The bylaw sets the rules for how waste is stored, collected, transported, and disposed of across Auckland.The council says the rules help keep footpaths clear of bins, reduce contamination in recycling, and ensure it collects the data needed to plan for future waste services.Regulatory and Safety Committee chair Cr Josephine Bartley says the proposed changes will not affect most people’s day-to-day routines.“It’s important we have clear and robust rules around how and where people can dispose of their waste and who can collect waste in our growing city,” she says.The council says the proposed changes are largely administrative and will not affect kerbside collections.It says they will help ensure waste is better managed across the region and that it has the data needed to meet long-term waste minimisation goals.Key proposed changes include:Expanding the range of waste facilities requiring a licence to include cleanfills and resource recovery facilities, while limiting the licence focus to data collection.Streamlining licensing rules for waste collectors, removing the current 20-tonne licensing exemption and adding exemptions for incidental waste services.Expanding approved options for waste disposal, such as supermarket soft-plastic drop-off points.Adding clearer rules to ensure waste is properly stored and contained on site, including for waste collection on private properties.Removing unnecessary or duplicated rules where matters are already regulated through the Auckland Unitary Plan.The proposal also recommends clearer explanations about approved containers, what can be placed in each type of bin, prohibited items, food scraps, use of public bins, and private-property collections.The council says waste collectors and facilities must continue to obtain a licence to operate in Auckland.Construction and demolition waste is not included in this review, with further investigation planned.Coasties can take part by visiting AKHaveYourSay.nz to view the proposed changes, find engagement events, and submit feedback.Know something local worth sharing?Send it to [email protected]

Inflation rises to 3.1%
Inflation rises to 3.1%

23 January 2026, 6:36 PM

Inflation has edged higher on the back of higher fuel, travel, and telecommunication costs backing the view the Reserve Bank will hold interest rates steady for the medium term at least.Stats NZ data showed the consumer price index rose 0.6 percent in the three months ended December, raising the the annual inflation rate 3.1 percent from 3.0 percent, the highest since June last year."While the annual inflation rate has slowed considerably since its most recent peak of 7.3 percent in the June 2022 quarter, it has increased each quarter since the December 2024 quarter, when it was 2.2 percent," senior manager of prices Nicola Growden said.She said price increases were widespread."More than 80 percent of the CPI basket increased in price over the past year - the highest proportion of increases recorded in 8 months."Domestic pressures easingDomestic prices - non-tradables - such as power, rents and rates remained the dominant factors for inflation, rising 0.6 percent for the quarter and by 3.5 percent for the year, but that was the slowest increase in more than four years.The 12.2 percent rise in electricity prices was the single biggest contributor to the annual increase, followed by an 8.8 percent rise in rates, and then rentals rising 1.9 percent for the year.Growden said annual electricity prices were at their highest since the late 1980s.The costs of purchasing a new house rose 1.2 percent for the year because of competitive pricing and cheaper fit out costs.The price of imported goods and services - tradables - rose 0.7 percent for the quarter and by 3 percent for the year, the highest since the end of 2023.The imported inflation rise reflected the high prices of fuel, the seasonal increase in international airfares, as well the high prices being gained for export food such as dairy and meat, and more expensive overseas accommodation.The inflation numbers were just above economists' expectations, and more than double the Reserve Bank's (RBNZ) dated 0.2 percent quarterly and 2.7 percent annual forecasts, which were made in November.Various measures of underlying inflation pointed to an annual rate remaining steady at around 2.5 percent.Expectations are the RBNZ has finished cutting the official cash rate, and the governor Anna Breman reaffirmed that was the most likely course, but emphasised the door would remain open for further cuts if the economy needed it.The consensus among analysts has been the RBNZ will hold the official cash rate (OCR) at 2.25 percent until early next year.However, there is a growing view that if inflation pressures are slow in falling, and a recovering economy threatens to add to them that the RBNZ may be forced to start raising the OCR as early as September this year.New Zealand's inflation rate was lower than Australia, the UK and the OECD's average of 3.9 percent, but above the sub-3 percent levels of the US and the European Union.Know something local worth sharing?Send it to [email protected]

WorkSafe Urges Safe Storm Cleanup
WorkSafe Urges Safe Storm Cleanup

23 January 2026, 2:07 AM

WorkSafe says Hibiscus Coast clean-up crews should treat post-storm work as high-risk and plan ahead.With clean up and rescue efforts underway in storm-damaged parts of the country, WorkSafe is urging workers to be aware of the risks that can follow extreme weather.Flooding, slips, downed power lines, debris and waterlogged ground can all change what’s safe, and what’s not.WorkSafe’s Acting Northern Regional Manager Jason Gibson says floodwater, silt and debris can be contaminated with farm run-off, sewage and chemicals.“For workers involved in the clean up, they need to take precautions like wearing appropriate PPE.”He says there’s also an increased risk of outbreaks of the water-borne disease leptospirosis, and workers should speak up if they feel unsafe.WorkSafe is also warning about households without power using portable generators and gas barbeques.“These should be used in a well-ventilated place so exhaust gases can escape safely, we don’t want people breathing them in,” Gibson says.As more recovery work rolls on, WorkSafe’s advice is to slow down, assume conditions have changed, and take basic precautions before the next job.Tips for staying safe during the clean up:If the work is not necessary, postpone it until conditions improve.Always assume that debris, flood water and silt is contaminated, stay away from it, or wear appropriate PPE.Minimise the risk of exposure to leptospirosis by washing your hands thoroughly and wearing PPE.Never use portable LPG stoves in a confined space and allow good ventilation for generators.Even if you know the land very well, waterlogged ground can be very unstable. Ensure you’re using the correct vehicle to move around, especially on farms.Make a plan to check in if out on a job, in case you run into trouble.If comms are down, have an alternative means of communication.Always assume downed power lines are live, stay away from them.If you notice things aren’t working when the power comes back on, get an electrician to check it out.Ensure fatigue is managed, businesses should monitor how long employees work, the sort of jobs they carry out and the conditions they’re working in.Know something local worth sharing?Send it to [email protected]

Survey Shows Sunburn Stays Common
Survey Shows Sunburn Stays Common

22 January 2026, 11:05 PM

Hibiscus Coast locals spend long summer days outdoors, and a new national survey shows sunburn is still common across New Zealand.The 2025 National Skin Cancer Survey found 64% of adults reported at least one sunburn last summer. About 26% reported a severe sunburn, defined as pain lasting two or more days or blistering. The survey sampled 2,198 adults aged 18 and over.Rates were highest among 18 to 24 year olds. In that group, 87% of females and 77% of males reported sunburn. More than one-third reported more than three sunburns over the summer.“Sunburn is an important risk factor for melanoma development, so these high rates are concerning,” said Dr Bronwen McNoe, lead author from the University of Otago.The survey points to gaps between what people know and what they do. Many people spend time outdoors during peak ultraviolet hours. Fewer consistently use effective sun protection.It also found misconceptions. Only 4% correctly identified the ultraviolet index level at which sun protection is recommended.Nearly one-quarter believed a suntan protects against melanoma and other skin cancers.Around one-third believed SPF50 sunscreen does not need to be reapplied as often as SPF30, or that a cap provides adequate protection.Attitudes toward tanning remain common.Half of respondents said they like to get a suntan. About 43% believed a tanned person looks healthier.Support for government action was strong. Between 82% and 90% supported investment in prevention, including SunSmart programmes, public education campaigns, more shade in public spaces and schools, and stronger sun protection policies in schools and workplaces.“The high level of public support provides a clear mandate for increased, sustained and coordinated investment in skin cancer prevention,” said Dr McNoe.Seen something local we should cover?Let us know at [email protected]

Woolworths warned it might be breaking the law
Woolworths warned it might be breaking the law

22 January 2026, 7:49 PM

The Commerce Commission has warned Woolworths New Zealand for what it believes is a likely breach of the Grocery Industry Competition Act, following a review of the major supermarkets' product delisting processes.The warning comes after the Commission analysed the range review processes of all major supermarkets to assess whether they were meeting their obligations under the Grocery Supply Code.As part of range reviews, supermarkets assess which products they will continue to stock. In some cases, products may be "delisted", meaning they are removed from shelves.The updated Grocery Supply Code is due to come into force on 1 May. The revised code gives suppliers clearer rights to challenge delisting decisions and greater transparency in their dealings with major supermarkets.Any breaches of the code are breaches of the Grocery Industry Competition Act.Commerce Commission head of groceries Dr Alice Hume said Woolworths, Foodstuffs North Island and Foodstuffs South Island together controlled about 82 percent of New Zealand's grocery market. She warned losing access to supermarket shelves could effectively be the end of the road for smaller suppliers."The possibility of products being removed from shelves is a significant weight on suppliers that can reinforce the power imbalance between major supermarkets and smaller suppliers," Hume said."The risk of losing market access can lead to suppliers accepting conditions that aren't beneficial to them, and a lack of trust about how supermarkets make these decisions."During the Commission's review, it identified and investigated instances where it considered Woolworths was at risk of failing to meet its obligations under the code.The Commission said it issued Woolworths with a warning for what it believe was a likely breach of the act, noting that only a court can determine whether a breach had occurred.Woolworths has since updated its processes to meet its obligations, the Commission said.In reply, Woolworths supplied the following statement."We take our obligations under the Grocery Supply Code seriously and we are proud of the strong relationships we have with our suppliers."We work hard to make sure we comply with all of our obligations under the code. If we become aware of potential issues, we fix them as quickly as we can."We reviewed and updated all of our templates when the code first came into force, but the Commission expressed concerns about whether one of our template letters included specific language that was required under the code."We fully cooperated with the Commission's enquiries, and have updated our template letter in light of the Commission's views."Levelling the playing fieldHume said the updated code played a crucial role in helping level the playing field between major supermarkets and smaller suppliers, and that the Commission took compliance seriously.She said range reviews remained an ongoing area of focus for the regulator.Hume also urged suppliers to come forward if they had concerns about delisting or other potentially unfair treatment."You can contact the Commission directly, or through the anonymous reporting tool on our website."Know something local worth sharing?Send it to [email protected]
