Luxon takes 'finish the job' message on final bus tour

National leader and Prime Minister Christopher Luxon has asked voters to let National "finish the job", repeating the message at every stop of his bus tour up the North Island in the final week of the campaign.

RNZ political reporter Lauren Crimp spent three days travelling with Luxon on National's big blue bus, from the Hutt Valley to Auckland. RNZ reported that Luxon used the bus ride to make a series of metaphors, many of them built around getting a task completed.

On the Wednesday, Luxon clipped off what RNZ described as "the Mohawk bit" of a half-shorn sheep. He told the crowd National needed three more years, because a job should not be left half done.

On the Thursday, he used clippers to finish shaving the half-shaved head of a Young National supporter. On the Friday, he hosed down the ute, or utility vehicle, of incumbent candidate Todd McClay and put the finishing touches on a cake decorated in National's blue.

The campaign's central argument is set out on the National Party website, which says the party's plan is working and that three more years are needed to finish the job.

National has also argued against the policy platform of the Greens. National's campaign chair said the Greens' fiscal plan, meaning its spending and tax proposals, included nine new taxes to fund $49 billion. The party has also argued that Chris Hipkins' pledge to resign rather than introduce new taxes was untenable, given negotiations with the Greens.

Luxon also addressed how people should vote. RNZ reported that he urged voters to avoid strategic voting, which is backing a party other than your first choice to keep a rival out, and used the word "malarkey" in making the case.

The bus tour began close to where Dame Jacinda Ardern quit as prime minister, the New Zealand Herald reported.
