crossed after nine phases of play.
That stung the Tui into action and winger Rakai McCafferty
showed great hands in grasping a low-flying pass to score out wide in the 27th minute.
Palu had featured in an earlier surge just before McCafferty touched down - a few minutes later the flying prop powered her way downfield in a 20m run through six defenders, to be brought down just short.
But the ball swung wide quickly to captain Krysten Cottrell
who touched down to make it 21-10 to Northland at the break.
Early in the second half, Subritzky-Nafatali scored again to push the Kauri out to 26-10.
The kick was missed, as was the Tui's conversion when Palu crossed after 52 minutes with an angled run of her own.
With 15 minutes to run, at 26-15 up, Northland were a player down after a yellow card.
Left winger Harmony Kautai
took advantage to make it 26-20.
The Tui swung back onto the attack, and No 8 Kathleen Brown crossed.
On a day when the goalkicking wasn't going well for either team, Brown had the presence of mind to regain her feet and head for the posts to improve the kick position for a one-point 27-26 comeback victory.
The Championship final is set to be played at 11.35am on Saturday although there is doubt around the later Premiership final with Waikato at an increased alert level as of Monday.
