But similar to what happened in New Plymouth in the previous round, simple errors and costly penalties saw Hawke's Bay with plenty of field position to score four tries in the first half to captain Ash Dixon, Caleb Makene and two to winger Neria Formai.
Northland stayed in the game through a Jack Straker try in the 22nd minute to keep the score at 22-15 at halftime. The home side's left wing was laid bare with three of the first half's four tries for Hawke's Bay scored down that side.
The visitors weren't at their best but recovered well after conceding the advantage to Northland early in the game. Remaining patient and waiting for their opportunities paid dividends for the Magpies as some slick passing was all it took to ensure a lead at halftime.
Whatever was said in the Northland changing room had an immediate impact as the Taniwha came out roaring at the start of the second half with a try to number eight powerhouse Jaycob Matiu after a barnstorming run from lock Sam Caird got the home side within metres of the line.
A Debreczeni conversion levelled the score at 22-all but with Makene scoring his second, Formai scoring his third and halfback Folau Fakatava scoring his first in the second half, the Magpies win was confirmed.
Two penalties from Debreczeni kept the Taniwha in the hunt with 20 minutes to go and only one point behind, but when it came to closing out the game, Hawke's Bay's unit, which hasn't lost so far this season, proved themselves as real contenders looking towards the back half of the season.
Speaking in a post-match interview, Taniwha captain Sam Nock said it was unfortunate to see the team's goal of a complete performance go unchecked but he thanked the crowd for their support.
"We spoke about putting out an 80-minute performance but we only put in about 20/30 [minutes] if that," he said.
"It's disappointing in patches but a lot to work on. Discipline has been our issue for the past three, four games but on the crowd, they are amazing, they are loyal fans."
Dixon, the Magpies hooker and captain, said there was a lot to work on before they return home for their next game.
"Our attitude wasn't quite right and Northland showed us how to play in that first 20 [minutes] and I was pretty disappointed how we just lagged through there, but full credit to Northland they bought their game tonight."
