I find the detail of this Wikipedia page to be amazing. It was shared 2 months ago (thanks @SamC). The main things that have changed since then are a continued slight dip in Labour/National and a slight rise in Maori/ACT.
If you have the time and energy then remember to read the policy proposals by the parties that you don’t like as well as the parties that you do like.
This is not scientific and is going purely by my memory but I don’t recall any small party getting the numbers the polls predicted. It’s always lower. People say they are going to vote for smaller parties but when it comes to voting they go for labour or national.
@BalpeenHammer @SamC it’s more noticeable with left wing small parties though? I notice it a lot with my boomer rellies.
It can happen but last time Greens did better than expected based on polls
