Advance New Zealand has been ordered to pull advertising that falsely claims vaccines are mandatory under the law.
The Advertising Standards Authority says the party's ad was misleading and ordered them not to use it again.
The flyer in question promoted the party with the words "Vote Advance NZ to reclaim
NZ back for all the people" on pamphlet's cover.
Inside the flier, alongside photos of the co-leaders and the families, the party laid out what it would do "for you and our proud nation".
