Pressure on ACT over past anti-vaccine comments posted by candidates.
Elaine Naidu Franz has resigned after creating a post comparing vaccine mandates to Nazi concentration camps.
Another candidate, Darren Gilchrist, has apologised for suggesting drownings were connected to the vaccine.
A third candidate called Covid-19 a ScamDemic.
ACT Leader David Seymour says the Nazi comment is unacceptable- and says he just disagrees with the others.
"If we're going to have purity tests and beat people down and have a 'right way' of thinking, that won't work. Because a whole lot of people, if they don't have the fashionable view, will find democracy's closed off to them."
