Elsewhere, a brace to loose forward Vini Iosua and some staunch defence, considering their lack of possession, saw Ardmore-Marist to a hard-earned 33-19 win over Manurewa. The home side led 18-0 at halftime, but had to withstand a fierce comeback from the visitors, who scored three tries.
A strong first spell saw Patumahoe trump Papakura 27-8, though the bonus point proved elusive.
Defending champions Bombay sent out a 41-0 warning to rivals. That was their scoreline against Onewhero, the club that upset them in last year's round one fixture. Steelers centre Sam Vaka and loose forward Haamiora Clarke were among the six tryscorers.
Waiuku also started on the right note, a bonus point, 26-14 victory over Te Kauwhata.
Next weekend's game of the week sees Patumahoe hosting Pukekohe, always a grudge local derby, while Bombay travel to Karaka. - Campbell Burnes
