About 3,000 people, including dozens of motorcyclists, most of them not wearing masks, passed through the capital's city center to join the New Zealand parliament.
Some attendees carried "Trump 2020" flags, while others carried Maori placards, or carried logans against lockdowns or supporting teachers who risk losing their jobs if they refuse vaccination.
Others targeted Prime Minister Jacinda Ardern with slogans such as "Pro Choice, Anti Jacinda", or the media.
The protest proceeded peacefully and broke up after protesters performed a haka in the Parliament precinct.
Police said there had been no arrests in Wellington, although they said they were disappointed that so many attendees were flouting the coronavirus restrictions.
Ms Ardern said most New Zealanders support her government's response to the virus, noting that nearly 90% of the population has received at least one dose of the vaccine.
"What we have seen today is not representative of the vast majority of New Zealanders," she told reporters.
The New Zealand government has adopted a severe response to the virus, with strict lockdowns and border closures.
New Zealand has recorded a death toll of 31 from Covid-19 for a population of five million.
Residents of Auckland, the country's largest city, have been confined to their homes since mid-August and Ms Ardern said this week those restrictions would be maintained until the end of November.

She has promised to introduce more freedoms, including an end to lockdown, when 90% of the population will be fully vaccinated.
However, those who are not yet vaccinated will still face restrictions on employment, travel and entertainment.
