"We are taking it game by game because these matches are really unpredictable", said captain Laura Langman. "Things can change in the second half, especially with power plays, so we don't count our chickens before they hatch. You don't really look at the score you just stick to your guns and get on with it. England are especially dangerous; they have grasped the game really well and their three point shooters are hot to trot."
Earlier the Ferns had enjoyed a huge 52-19 victory over South Africa and a comfortable 44-24 win over Malawi.
Against the Proteas coach Wai Taumaunu again took the opportunity to use her full lineup, with second stringers including Bailey Mes and Anna Thompson starting the match and getting plenty of court time.
The Ferns were too strong across all areas of the court and two long bombs from Maria Tutaia - much to the crowd's delight - in the powerplay quarter took New Zealand past the half century mark.
In their earlier match New Zealand demolished Malawai 44-24, with Tutaia again the standout with several outstanding long range shots from distance.
The African side were expected to provide a tough test, especially after their convincing victory over the Australia on the first day but struggled against the height and reach of the home side.
In other results on day two Australia, whose team of rookies have been the flops of the tournament, crashed to two more defeats, 28-27 to South Africa and a 34-33 reverse against Jamaica.
The Jamaican win sealed their place in the top four, while South Africa beat Malawi (48-34) in the penultimate game of the day to grab the final playoff spot.
