Three Te Pāti Māori (Māori Party) MPs who took part in a haka within Aoetearoa's Parliament have been suspended from the house, two for 21 days and one for seven days, following hours-long debate on Thursday.

In November, MP Hana-Rawhiti Maipi-Clarke rose and tore the controversial then-proposed Treaty Principles Bill before beginning a haka, joined by Te Pāti Māori co-leaders Debbie Ngarewa-Packer and Rawiri Waititi.

The protest became a global news piece, performed in response to the first reading of the Treaty Principles Bill, which sought to redefine the Treaty of Waitangi.

In Parliament on Thursday, members voted to uphold Privileges Committee proposals to suspend the party co-leaders from 21 days of service, and Ms Maipi-Clarke for seven days of service.

They were each suspended, the co-leaders also "severely censured" for "acting in a manner that could have the effect of intimidating a member of the House and the discharge of their duty".

The outcome had been delayed since initial debate was suspended on May 21, cited as to allow the three MPs to participate in the country's budget, scheduled for delivery in the same week.

Thousands gathered in protest outside parliament on the scheduled vote date.

On Thursday parliament debated the proposed punishments in the house for three hours before votes were cast.

The suspensions carried with votes in favour from coalition government (National Party, ACT Party and New Zealand First) members present, with Labour, Green Party of Aotearoa New Zealand and Te Pāti Māori against.

Amendments presented during the debate had not been carried prior to the final vote.

The proposed suspensions had been labelled an example of conservative coalition extreme partisanship by the other side of the house during debate.

As first suspended, Ms Maipi-Clarke was unable to participate in the vote concerning Ngarewa-Packer, who similarly could not vote on Mr Rawiri Waititi's outcome.

According to Radio New Zealand (RNZ), more than half of respondents to a public survey had supported bans for the MPs.

37 per cent of respondents felt the proposed suspension were 'about right' joined by 17.2 per cent who felt they were 'too lenient', according to an RNZ-Reid Research poll.

36.2 felt it was 'too harsh' while 9.6 per cent responded 'don't know'.

A number of Māori MPs from various parties spoke to the house during debate.

Green Party's Marama Davidson described the Treaty Principles Bill as "designed to provoke" and an example of "political violence", as she opposed the suspensions.

"The very least it deserved was that passionate haka," she said.

Labour's Willie Jackson argued suspension of one day was enough, he felt had already been served by Ms Maipi-Clarke, having congratulated Te Pāti Māori "for the greatest exhibition of our culture in the house in my lifetime…because we had the greatest threats to Māori-Crown relationships in my lifetime".

A number of MPs opposing the ban had argued their less-involved participation in November's incident had resulted in no punishment.

The proposed suspensions of seven and 21 days, respectively, were compared to the previous record suspension of three days given to a member of the parliament.

Non-Māori Green Party MP Chlöe Swarbrick called the punishments "punitive nonsense" stating "this would be a joke, if it wasn't so serious".

Her party colleague and first term Māori MP Kahurangi Carter said the decision threatens to "swipe away" Aotearoa's history and reputation of empowering its Indigenous people and culture.

"I urge members to consider what legacy we leave behind in this house," Ms Carter said.

Māori Labour MP Adrian Rurawhe said "There is no winners in this debate" and "it's demonstrably clear to me that it is the government that is punishing the members today, not the parliament".

Minister for the Prevention of Family Violence and Sexual Violence and Māori ACT Party member Karen Chhour said "what we're addressing is conduct within the house" adding her support to the Privileges Committee's recommendations.

Minister Chhour added lack of remorse or contrition from the three MPs Te Pāti Māori was a factor in her leaning.

Maori ACT member Nicole McKee also gave her support to the suspensions.

The Treaty Principles Bill, first introduced by ACT leader David Seymour, was voted down in a landslide in April, after widespread public protests in Aotearoa and around the world.

Speaking during the debate, Ms Maipi-Clarke reiterated her words from weeks previous stating "the issue is not our response to the problem".

"It was unruly, disorderly, uncivilised to bring in a treaty principles bill. It was a dishonorable vote," she said.

"When we stand up for the country's foundational document, we get punished twice with the most severe consequences in the world," Ms Maipi-Clarke said addressing the parliament, also adding her party "have no option but to be the opposers and proposers at the same time and actually address the core problem that these systems represent, so that another generation doesn't have to come through these doors and be silenced".

Te Pāti Māori co-leader Rawiri Waititi said haka is "an elevation of our indigenous voice, a declaration that Maori will never surrender the mana (power) of Te Tiriti o Waitangi" and "history tells us that when Māori refused to play ball, the coloniser reaches for the maximum penalty. Just as this house does today".

Party co-leader Debbie Ngarewa-Packer had stated "this is not about disorder; this was just about us standing in our truth".
