The ACT Party has intensified its rhetoric against what it calls race-based law.
The party has previously said Maori get too much preferential treatment, and has criticised the National Party for what ACT calls separatist and racist policies.
In a recent speech ACT leader Jamie Whyte said New Zealand law makes a citizen's rights depend on their race, and that Maori are legally privileged in New Zealand today.
He said one of ACT's core principles has always been that the law should be colour blind and should treat everybody equally.
On Wednesday told Morning Report Whyte cited the Maori seats in Parliament and Auckland Council's Maori Statutory Board board as examples.
And New Zealand First leader Winston Peters says his party won't be part of any post-election deal in September involving either the Maori Party or Mana.
As the election draws closer, political parties are coming under more pressure to declare who they will, or won't, work with after the election on 20 September.
The Maori Party is a more likely bedfellow for National, and Internet Mana for Labour.
Peters told reporters on Tuesday New Zealand First would not be part of any governing arrangement that includes race-based parties the Maori Party and Mana.
“We've made it very clear - we think that separatism is extraordinarily damaging for this country. I know a lot of you think it's fair enough you'll go along as cultural fellow travellers - well, it's disastrous for New Zealand. We're going to keep on saying it.”
Peters said staying on the cross benches is still an option.
