This week, distinctive orange envelopes will begin arriving in mailboxes across Aotearoa.

This time around, they'll hold the voting papers for the local government elections.

But what are the rules?

And what do the strange acronyms mean?

Read on for the essentials on how to vote, what you are voting for and when the all-important results will drop.

Can I vote as soon as my voting papers arrive?

You sure can. Voting papers will be posted to enrolled voters from Tuesday [September 9] to September 22.

You can complete your voting papers as soon as it lands in your letterbox but Tuesday 7 October is the last day for posting your vote by mail.

After this date, votes must be returned to a council ballot box by midday, 11 October.

What am I voting for?

Local elections are held every three years for regional, city and district councils.

You can also vote for the mayor, and some residents vote for local and community boards.

For this election, some councils that have Māori wards will be holding polls on whether or not voters support keeping them.

Who should I vote for?

Well we can't answer that.

But if you're undecided or don't know who is running you can head to the website policy.nz.

It provides candidate profiles and policies in a single place.

Just tap in your address and you're given the local options.

Website co-founder Ollie Neas said the website aimed to combat falling voter numbers and inform people, so the elections didn't turn into a game of 'Guess Who'.

Also look out for local candidate events, news stories and pamphlet drops.

STV or FPP - all about the acronyms

Most councils use First Past the Post (FPP), while 15 councils use the Single Transferable voting (STV) system.

In First Past the Post, the candidate with the most votes wins.

You get one vote and that vote goes to one candidate.

For single transferable voting, you rank candidates in their order of preference.

You would write "1" next to your favourite candidate, "2" next to your second favourite and so on.

With STV you still only have one vote but by selecting your preferences for all the candidates, your single vote can be transferred to your next favourite candidate if your most preferred candidate doesn't need all their votes to be elected.

I've filled out my voting paper. What next?

You can drop your voting paper in a post box, an orange voting bin provided by your council, or deliver it in person to one of the council's voting hubs.

Councils list the locations of their orange voting bins on their individual websites.

You can also post your voting paper at a post box.

Check NZ Post's website for you nearest post shop.

What if I'm not enrolled?

You'll need to enrol before voting.

Head to the vote.nz website and either enrol online or arrange for enrolment papers to be sent to you.

You will then need to cast a 'special vote'.

The best way to do this is to look at your council website.

Councils will have a special voting location to cast a special vote, or pick up a special voting pack.

If you can't make it to a special voting location, the council can send your special vote papers to you.

If you didn't receive voting papers then you'll need to cast a special vote too.

My dog ate my voting paper

If your voting papers are damaged or destroyed, then you'll need to cast a special vote.

Here the exact same process applies as above.

This seems like a lot of effort. Why should I vote?

LGNZ president Scott Necklen said council decisions touch on our everyday lives, from flushing your toilet to the local rugby field.

Councils are also making long-term decisions that impact children and grandchildren.

"Take the time to think about what's important to you and your family," he said of voting.

When will we know the results?

Progress results will start coming in from noon on 11 October.

Declaration of results will be released from 16-22 October.
