Tongan rugby league fans protest again

A small group has gathered in downtown Auckland, where a protest by Tongan rugby league fans is due to begin.

Supporters are irate over a referee's call they feel robbed their team of a spot in the Rugby League World Cup final.

A social media post shared online today said last night's march at the same location received media exposure and urged supporters to again turnout on Quay and Queen Sts in the CBD to push World Cup organisers to take another look at the refereeing decision.

As of 6pm, the protest's advertised start time, there were just a handful of supporters waving flags and dressed in red.

Hundreds of protesters were in the city last night, singing and dancing through the streets.

The committed few currently on Quay St were more subdued and were sitting and talking.

Police said they were aware a number of Tongan supporters "are keen to have another gathering this evening".

"Police are keen for the public of Auckland to be able to go about their business, and any ad-hoc celebrations will likely have a large impact on commuters," Auckland City District Shift Commander, Senior Sergeant Matt Rogers said.

"Police have a number of staff in the area who will deal with any matter as required."

Senior Sergeant Rogers said police were also aware of social media reports that the King of Tonga was supportive of and encouraging the protest.

"This is not the case."
