After a 50 metre penalty from Ryuben Vaipo to open the scoring Tauranga settled into their work. Quick thinking from Mua set up hardworking flanker Matt Ensor for a try in the corner converted with some style by Trask.
A penalty each saw Tauranga ahead 10-6 before the try of the match for Tauranga from a set piece with some slick passing and sharp insertion from fullback Steve Honey gave rampant bulldozer Paula Narawa a try in the corner.
Whakarewarewa scored early in the second half from an intercept try to their outstanding openside flanker Sioeli Alofi to temporarily fire up a strangely deflated Whakarewarewa unit.
But two tries in two minutes to flanker Dan Crowther and replacement prop Tevita Mafileo made the game safe for Tauranga Sports who spent the last 20 minutes camped in their opponent's half.
Tauranga Sports coach Zane Winslade says getting his forward pack primed for Whakarewarewa was the focus during the week.
"I just think they did really well around the park, all eight of them just working really hard on defence and that is the thing I was most pleased with," he said.
Winslade knows he has a couple of special players at 8 and 10 who continue to impress after making New Zealand secondary school teams last year.
"They are developing well. Ajay is a quality player and Kaleb too and they are both stepping up. In those positions you need to lead and as young guys they are able to do that in our team.
"It is awesome to have young guys that can come straight out of First XV rugby into leading club rugby which is pretty beneficial for us."
Whakarewarewa's coach Joe Savage was struggling to find a reason for his team's lacklustre performance in a game they usually fire up for.
"We prepared pretty well during the week but going into the warm-up we seemed a little bit flat. I think it must have been the van ride but the game just didn't go our way," Edwards said.
"We normally get up to play (Tauranga) here and it is one of the things I am puzzled about. We definitely got up against Mount Maunganui last weekend and we were very much looking forward to the game this weekend."
