"We can't complain too much or keep going on about it, otherwise we are going to lose focus on what's at stake this weekend - it's just another hard game that's all."
Leading with around 10 minutes to go last week against the Mount, the game ended in a 24-21 defeat.
"There are always positives from every game, but for us - especially last week when we were leading 21-13 with about 10 minutes to go - we've just got to learn to put teams away."
Ill discipline was Whaka's biggest enemy last week.
"That cost us right at the dying stages and we let them score and gave away a couple of penalties and a penalty on full-time and obviously that cost us. If you don't start to rectify these things, you're just going to keep travelling down the same track."
Irihei said there are no secrets to what Tauranga Sports will bring to the table tomorrow.
"They are probably the best structured team in the competition. Everything they do at set piece, their line out, their scrums, and their field play, are probably the best, that's why they won the competition last year. "We've certainly got the backs, we've proved that in the past, and our forwards have to keep on going the way they have been and get some dominance. That's where there's a lot of focus, to get our forward pack to match the likes of Tauranga and the Mount and Te Puke because that's where they had it over us and we've made huge inroads in that area.
"We're not too far off, but a win is always good because when you're losing by one or two points it certainly doesn't help the cause."
Regular goalkicker Ryubyn Vaipo, who missed last week's game, is out again, but Whaka have an able replacement in Te Rangi Fraser who slotted three conversions from three attempts last week. Jordan Lay returns after a one week concussion stand down and lock Tamati Rhind may make his return after a hamstring injury.
