Winger Tori Iosefo deserved her hat-trick. The support play from the backs inside her was superb with Black Ferns first five-eighth Krysten Cottrell classy in all aspects of play.
Centre Te Maari MacGregor had her best game of the season while former Black Ferns halfback Emma Jensen again displayed the benefits of her vast experience.
Meanwhile, the Hawke's Bay Saracens won their Hurricanes Development competition for a third consecutive year with a 100-15 drubbing of Manawatu Development in the final encounter of their round-robin at Napier's Park Island on Saturday.
Second five-eighth Neria Fomai was electric in the midfield and scored a hat-trick.
Saracens manager Tim Jones said Fomai was putting his hand up for a Magpies contract.
Hooker Jack Nelson-Murray and flanker Damien Scott again had high work rates in the host pack.
While the Saracens were unbeaten in their competition, Jones said they are expecting a tough encounter when they host the Wellington Development team at Park Island this weekend.
