Like all followers of North Harbour rugby, Tuioti-Mariner knows that inconsistency has been the side's bugbear in 2015, patches of good rugby interspersed with errors and poor decision-making, exemplified by Saturday night's 31-17 defeat to Manawatu.
"We've got to be more consistent, 1-23. We need to front for the last 10 minutes of the first half and the first 10 of the second half. We have to get up for Otago on Thursday night, because they'll be gunning for us."
Harbour coach Steve Jackson, a former Massey club lock himself, has taken real pleasure in seeing Tuioti-Mariner's rapid progress over the last 12 months, and says he is a shining example to others in the squad of the rewards if you apply yourself in ITM Cup.
"I'm rapt for him to be in the Blues. He's a good ball carrier, runs hard, good lineout forward and its hard in the collisions. He doesn't say too much, but he does a lot with his actions. He's a good man," said Jackson.
Now Tuioti-Mariner needs to give more of the same against Otago at home tomorrow night to help hand his team a Championship semifinal lifeline. That will be his 14th game for the union, just one short of a blazer that will be richly deserved.
