The main survey, which people can complete online in English or te reo Māori, takes about four minutes, with an option to answer supplementary questions, and is aimed at everyone eligible over 16.
"We're not too worried about getting a representative sample in this survey at this stage, we just want diversity," says Greaves.
"Just chatting to people about their decisions, we think it's likely there will be a huge variety of reasons people have, alongside some common thoughts."
The survey also includes a six-question multiple choice quiz where people can test their knowledge about voter enrolment.
"We would like to think this is a fun way to learn a bit more about voting, but it's also helpful to be able to find out where there are gaps in people's knowledge about roll choice, gaps that we can pick up on in education work."
The main goal of the research is to create an online resource that Māori voters can consult when making the choice for themselves.
The survey is being rolled out by a team of young Māori researchers who are all getting valuable experience in the process, says Greaves.
"That's been one of the best things about the whole project so far."
It will be open to complete from 20 July to around October 2022, and strongly promoted via social media.
