Labour could send targeted direct mail to anyone on the general roll who turned out to vote in strong Labour areas at either of the last two elections, and urge them them to vote for Peters. Better still, they could send in volunteers to knock on their doors to convey the same message, as well as make sure they show up on Saturday.
A few grand, couple of minivans, bit of shoe leather. What a modest investment to help get a key future coalition partner across the line.
Everyone seems convinced the latest Roy Morgan poll, which has Labour at 31 percent, is a great result. It still looks ten points shy to me – if it's a "honeymoon", it's the third marriage/Dannevirke Motor Inn variety – but if I'm dreaming, and Labour really has become a 30 percent proposition, then it's clear we need NZ First to (a) perform strongly and (b) prefer us to the Nats. Peters winning Northland with Labour's potentially decisive assistance could help on both fronts.
If Labour puts in late push for Winston, and he wins, the party can legitimately claim some of the credit. If Winston still loses, Labour can at least avoid some of the blame, despite its hopelessly muddled half campaign to date.
Winston has all the momentum but none of National's organisation on the ground. Labour is ideally positioned to close that gap, and the advantages of doing so are many and obvious.
If Labour are worried about accusations of deal-making and dirty politics from the sanctimonious blowhards of the cyberleftysphere, they should remind themselves how helpful those geniuses have been to date.
