Mose Tupaea has pleaded guilty in Hutt District Court for his racist actions on a public bus service.

A Wellington pensioner who unleashed a racist rant on a Wellington bus last week has pleaded guilty to two charges in relation to his tirade.

Moses Mohi Joe Tupaea, 66, of Avalon in Lower Hutt, admitted two charges relating to the March 25 incident, including threatening to injure one of the fellow bus passengers, Pene Walker, and using offensive behaviour.

Tupaea has been remanded at large until May 12 for sentencing, and to discuss the possibility having a restorative justice meeting with the victims.

The incident was captured on video by a fellow passenger sitting behind Tupaea and posted on various websites, which prompted outrage at his racist comments to two young male passengers and a nasty verbal attack against Walker, who had defended the two men. It occurred on the Valley Flyer bus between Petone and Naenae.

Inspector Tracey Thompson, Wellington district Maori responsiveness, said outside court that Tupaea's arrest over allegations of racial abuse reinforced that such behaviour was unacceptable in our communities.

She thanked members of the public who helped with the police investigations.

"The community response in itself is a clear message that our communities will take a stand when incidents such as this occur.

"Everyone in our community has the right to be safe and feel safe as they go about their daily business."

She said police vowed to thoroughly investigate allegations of racially motivated abuse or violence, and appealed to the public to notify police if they became aware of such issues.

Tupaea also apologised outside of Hutt Valley District Court on Tuesday. It was the first time he had had such a rant, he said.

"It won't happen again. I shouldn't have said it."

He said his opposition against Islam was because two of his friends, who he declined to name, were hostages in the Sydney Lindt Cafe seige.

Pene Walker, who confronted Tupaea on the bus, said it was nice to hear him say guilty, but she doubted wanting a restorative justice meeting with him.

"It's a bit ridiculous meeting the guy if his attitude isn't going to change."

Walker said she would step forward again if a similar incident occurred.

A stranger has come forward and offered to pay for Walker to have dinner at a Wellington restaurant and night's accommodation as way to thank for standing up against racism.

Noor, the 21-year-old Muslim woman who videoed the exchange on her cellphone, said she was pleased Tupaea pleaded guilty to the two charges.

Ironically, she spotted him travelling on the same bus with her on Tuesday morning, most likely on his way to court.

"I was scared to see him. He was looking at me but he didn't say anything."

She said she would agree to face him at a restorative justice meeting, if it was held before she moved to Australia in about two weeks' time.

"It's good if I meet with him because someone needs to set him straight about Muslim people.

"You can't really judge all Muslims for some idiots who did something."

She also said he was wrong to speak to Walker in such a nasty way.

"I can understand why she doesn't want to meet him."
