Protesters are planning to camp outside an unconfirmed Auckland venue where two far-right speakers are due to appear on Friday night.
The group hopes to show Lauren Southern and Stefan Molyneux that multiculturalism is celebrated in New Zealand.
They're not welcome in Aotearoa.
Tamaki Anti-Fascist Action spokesperson Sima Brown-Davis says they will move from Aotea Square to the speakers' venue.
"People will be demonstrating their cultural items, doing a haka while they're speaking inside and then while they're coming in and out," she said.
Ms Brown-Davis is concerned about what will be said at the speaking event, following reports Mr Molyneux made racist comments at an Australian event in July.

- New Zealand is anti-free speech - Lauren Southern
- Southern has right to come and speak, but not at council venue - John Minto
"Stefan Molyneux did a whole dialogue which was quite dehumanising of aboriginal people, we're really concerned that he's going to repeat the same sort of racist talking points against Māori in Aotearoa," she said.
The protesters represent community, cultural and activist groups and Ms Brown-Davis said they're planning to demonstrate tolerance.
"They're not welcome in Aotearoa," she said.
"We have no room for racism and that Auckland is a diverse city that honours the tangata whenua."
