Mana Party leader Hone Harawira says he was just sitting in his car listening to music when police smashed a window and pulled him out amidst an Auckland protest over state housing cuts.
The Te Tai Tokerau MP was arrested late on Thursday night alongside seven others after about 40 protesters tried to stop a state house being moved from Glen Innes to Mt Wellington.
Several protesters were on the house's roof and in its ceiling.
Harawira reportedly parked over the driveway of the house being removed.
Police smashed the back window of his car to pull him out.
Mr Harawira says he doesn't believe he was breaking the law.
"I was only parked in the car, listening to some music, supporting the people who were up on the houses and the police chose to break the window and arrest me," he told Radio New Zealand.
He said he didn't go to Glen Innes to get arrested or debate the law, and he did not know if he would do the same thing again.
It was unclear what the charges against him were.
Mr Harawira says those involved in the protest are heroes, "on behalf of New Zealanders who are opposed to the destruction of state housing all around the country".
Housing New Zealand is removing 156 state homes from Glen Innes and replacing them with 260 high density homes and apartments as part of the Tamaki Transformation Project.
Mr Harawira says the agency has no plans for the families living in those houses.
"All they're doing is knocking down their homes, or picking their homes up and removing them from the territory. They don't have any plans to house these people, they only have plans to sell up the land to their property developer mates."
Meanwhile, Mr Harawira wrote on his Facebook page that he was heading to Kaikohe on Friday morning "for a real breakfast" with beneficiary Sam Kuha, who is ending a 30-day hunger strike after Social Development Minister Paula Bennett agreed to meet him and discuss his problems.
Mr Kuha began his hunger strike after being told he had received three food grants and wasn't getting another until he sought budgeting advice - although there was a two-week waiting list.
In a statement, Mana Party president John Minto said it was a peaceful protest, and those taking part were heroes.
"They have laid their bodies on the line against the might of the government who are determined to evict people from their homes," he said.
"Hone has been involved for some time standing alongside a community that is against the Government acting on behalf of private developers that want to rip the heart out of their community...
"The Government is simply adding stress to the lives of people who are already struggling to make ends meet."
