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."
