The Black Ferns will take the 40-22 win over Canada, but they know there is much to do to take down England in their next match of the women's Super Series on Thursday.
In warm conditions in Calgary, the Black Ferns scored seven tries to four in an open clash, but they were pressured in the opening quarter and in the scrums by a committed Canadian outfit.
The score might have been much higher were it not for No 9 Kendra Cocksedge kicking only two from seven off the tee, though she played very well around the field and took the official player of the match gong.
Black Ferns debutant blindside flanker Charlene Halapua opened the scoring after just five minutes on the short side, before wing Honey Hireme swung into action, showing her sheer pace for an impressive brace.
Second five Chelsea Alley was also prominent, making several thrusts in the midfield and scoring a try of her own.
