Coach Steve Jackson is down to his third-string halfback Luke Hamilton, a jaunty competitor who will feed Matt McGahan in the No 10 jersey.
Luke Devcich, who has been outstanding at times in 2014, replaces Nafi Tuitavake on the wing. In the pack, Jordan Manihera slots in at No 6, Mike Farmer at lock, and Zak Judge on the openside flank.
"We thought the boys lacked a bit of energy last week, so hopefully Jordan will bring that," said Jackson.
Despite the flogging, North Harbour did secure a bonus point for four tries, which may prove invaluable today. But the attitude and focus will need to be ramped up today, or a Lions outfit desperate to salvage something from a wreck of a season could dampen their ardour.
"We were bad (against Northland). I know the players know they were bad. We were lethargic and fell off tackles," Jackson said.
"The rugby gods did us a favour last week. Our fate is now in our hands. If the guys want to be in the semis we have to win. But I don't care what the results have been, Wellington will be tough at home in their last game. They've got about four Super Rugby players in their pack, and guys like Motu Matu'u and TJ Perenara are back. Brad Shields has been holding them together as captain."
North Harbour has produced the goods on most occasions in 2014, and lock and skipper Hayden Triggs has been in the thick of it.
"I'd be really disappointed if Triggsy didn't make a Super Rugby side," declared Jackson.
• Auckland require simply a bonus-point win over Northland at Eden Park tonight in a crossover clash to secure their Premiership semifinal berth. The Taniwha have not beaten their big Blues cousins since 2008, but have been in stunning form at times in 2014 under the coaching of Derren Witcombe. They are already safely into the Championship semifinals.
Counties Manukau will know if their season is still alive by about 9.15pm tonight, and then they can set about taking down the Makos in Blenheim.
