"I started for the Chiefs and I want the No 7 jersey for the New Zealand Secondary Schools team," said Mua, who is Bay of Plenty-bound next year.
Fullback Danny Toala, who scored 29 points for Hastings, again enhanced his chances of NZSS selection. He scored three tries and kicked seven conversions from nine attempts at goal in tricky windy conditions. This was Hastings Boys' High's 15th consecutive win from as many matches this season and their 31st win from their last 32 matches.
The school has scored 924 points in their 15 outings this season while conceding 50.
HBHS manager and former Magpies halfback Jason Bird said there was some rust in the hosts' display in their first outing after the school holidays and he stressed the importance of the coming week to his troops.
"This is going to be a huge week. We're unlikely to get a harder assignment than this."
It took Tauranga 30 minutes to get into the Hastings half during the first spell and what little ball they managed to secure they dropped before completing two phases. This was a tribute to the in-your-face defensive work of the hosts more than the cold weather.
Second five-eighth Sione Faiva made the most of his limited opportunities for Tauranga.
Napier Boys' High School beat New Plymouth Boys' High School 45-22 in Napier after leading 17-10 at halftime. NBHS assistant coach Dave Russell said his troops ran in some good tries in an ideal rehearsal for Wednesday's away Polson Banner challenge against Palmerston North Boys' High School.
Winger Dan Sharplin scored three tries. Halfback Humphrey Sheild and centre Tyrone Dodd-Edwards were others to shine in the Napier backline. Tighthead prop Cam Huata, captain and blindside flanker Josh Bokser and No 8 Lolani Faleiva were all prominent in the hosts' pack.
