About 1000 Tongan league fans have marched down Queen Street in Auckland, bringing traffic to a halt.
The fans say a decision by the referee during Saturday's Rugby League World Cup semi-final against England robbed Tonga of the win.
England held off an astonishing late fightback from Tonga to reach the final for the first time in 22 years with a 20-18 victory in Auckland.
Fans eventually gathered outside the Grande Mecure hotel on Customs Street East - where the Tongan league team is staying.
The police are monitoring the crowd and have stopped cars that fans are standing on top of as they drive through the city.
Protest organiser John Ulele said he organised the protest because he was not happy with the turn out at Sunday's protest.
He said he told protesters that organisers didn't want people to go on the roads or dance on the roads because they didn't want the police to interfere.
"But the police they said they would be fine with us standing on the sides of the road until we marched and then they would give us an escort - which they did."
Mr Ulele described the turnout today as amazing and stressed that it was not a celebration.
"Tongans and protests do not go well together, they make everything look like it's a celebration, but it's not, it's a protest."
Earlier protestors in Aotea Square chanted 'give us our win' and sang to passersby.
One woman said the team and the fans had been robbed to a chance of the final by a bad referee decision, which should be over ruled.
RNZ reporter Sally Murphy said fans carrying flags and banners were dancing in the street disrupting traffic.
One man surfed down the street on top of a car, she said.
In a statement, police said some social media reports had intimated that the King of Tonga was supportive of the gathering but that was incorrect.
