Inspector Pat Handcock, the area commander at Palmerston North police, today said investigators were still determining if Taane was singing a song or directing his comments at officers.
"At this stage we're just going back through some of the various accounts of people that were there. We'll make an assessment in terms of exactly what happened and whether or not Tiki Taane has transgressed the law," Mr Handcock said.
It comes as an encore to the almost identical performance that saw Taane arrested last year during a gig at Illuminati Superclub in Tauranga.
Taane, who had again chanted "f*** the police", had charges against him dropped after he explained he was singing the same NWA song.
Despite a repeat of trouble, the singer has retained the support of power company Mercury Energy, which hired Taane to cover the song Over The Rainbow for an advertising campaign and contribute all proceeds from sales of the song to the Starship Foundation.
Mercury Energy general manager James Munro yesterday said the company was "really pleased" to have had Taane cover the track for their campaign.
"Tiki has a good relationship with both Mercury and the Starship Foundation and has been, and continues to be, generous with his time in helping to raise money for sick children," Mr Munro said.
Starship Foundation chief executive Brad Clark also stood behind Taane, saying the foundation was "grateful for Tiki's generous and heartfelt support".
Mr Handcock said an internal inquiry would discover by the end of the week if there was any cause for a full investigation into Taane's behaviour.
He said the accounts of the police officers who were present at the club would be compiled for a clear picture of the events.
Taane could face a charge of disorderly behaviour likely to cause violence or disorder.
"I reiterate we are just looking at what happened and if it turns out to be ... nothing we are not going to pursue it and waste time and resources on it by going out and trying to locate a whole bunch of other witnesses and things like that," Mr Handcock said.
"But if there is something in it that would suggest a criminal offence has been committed, we would be required to make some further investigations."
Dancers dressed as police officers joined Taane when he performed his song Freedom To Sing at last year's Vodafone Music Awards.
The move was described as Taane offering an olive branch to officers he'd previously offended.
Taane has previously worked with police to front an anti-family violence campaign, Mr Handcock said.
The inspector said it was important police evaluated the weekend's incident with "an objective view of what happened in the context of the evening".
"At the end of the day we want licensed premises to conduct their business safely - safely from the patrons' perspective as well as for police," Mr Handcock said.
