Old rivals Hamilton BHS and Rotorua BHS will again contest the Chiefs Cup final after the latter edged Wesley 9-5 and Hamilton BHS defeated 2016 CNI champs St Paul's Collegiate 35-14.
There were some topsy-turvy results in the North Harbour 1A competition. Westlake BHS had contrasting victories, a 94-0 midweek hiding of Takapuna Grammar followed by a much tighter 14-0 result over Rangitoto on the weekend. Massey suffered two reverses, 30-9 to Rangitoto and an 8-0 boilover versus Birkenhead.
There was also a boilover in the Auckland 1A, where St Peter's edged St Kentigern, not for the first time in recent seasons, 11-10. MAGS could not christen their newly named BG Williams Field with a win, falling 21-12 to rivals Auckland Grammar. Dilworth, with three straight wins for the first time ever in the 1A, are still atop the table after three rounds, on points differential from Sacred Heart, who beat Kelston BHS 27-8. Dilworth won 20-3 over Aorere.
The next televised game is tomorrow's traditional from the deep south: Southland BHS v Otago BHS. The latter tuned up with a 32-5 win over King's HS in another traditional.
There was snow and sleet in John McGlashan's 26-5 victory over Mt Aspiring.
