Her switch was welcomed by Te Pati Maori president John Tamihere who said she was crossing the floor to her own emancipation — walking away from a sure thing and doing it “for the mana of our people”.
Whaitiri said she was acknowledging her whakapapa and the calling of her whakapapa. The move was effective immediately.
She did have ministerial responsibility for the Hawke’s Bay cyclone response after Stuart Nash was sacked. There are, however, bonuses for Labour in her decision.
Polling indicates that Labour will need the support of more than the Green Party if it is to win a third term in the October election.
In that sense its key prospective ally would be Te Pati Maori. Despite the odd contretemps, the two parties are philosophically close and are reported to have been meeting together regularly.
Polling has bounced around for Te Pati Maori but Whaitiri’s move will be a significant boost. She is likely to secure another electorate seat and the party an invaluable three to five seats for a Labour-led coalition.
The timing of her announcement means there will be no need to hold a by-election, because an election will be held within six months of her resignation — as is also the case for Jacinda Ardern in Mount Albert.
So while it is not a good look for the Government, Whaitiri’s switch is far from a disaster for Labour.
