New Zealand First's Shane Jones told media that Winston Peters had a long history of coming to Waitangi, and a "robust fiery response" was not unexpected.
"Why would anybody be surprised? I'm not," he said when asked about Peters' combative comments.
"I think both Winston and I know, people have pent up emotions ... people are on edge."
He said there were a lot of views within Ngāpuhi but that they usually came together when there was a common foe, and he hoped that he didn't represent the common foe.
The crowd were "unnecessarily rude" to Act's Nicole McKee, Jones said.
"But hey, young people, I was young once, out in the hot sun you can get carried away."
On being called out by Annette Sykes, he said they had gone to university together and she had made an art form out of calling him out.
Jones also defended Luxon's speech, saying the prime minister was asked to talk about the country in 2040.
"I didn't think it was off colour at all."
He also spoke about Peters' history: "Respect goes two ways and Winston has a long-established history of fighting and delivering [for Māori] ... I think that's what he was responding to."
"There's going to be a lot more political water under this bridge," he said, adding he was going to take up a bigger role in the debate about the Treaty principles.
There were 57 references to treaty principles in legislation, he said.
"Are they all relevant?"
He said nothing the Government was doing was delegitimising "what it means to be Māori".
Opening up a debate on the role of the Waitangi Tribunal and looking at the relevancy of the Treaty principles in a contemporary setting did nothing to imperil what it means to be Māori, he said.
When asked about Luxon reading off cue cards, he said not everyone had the same gifts of oratory.
Helen Clark read off cards, he added, though Sir John Key didn't need to.
However, he added a jibe at Key, saying "then again everything he said was blown away by the wind" and that was why people questioned whether he'd left a legacy.
