The Fast5 Ferns topped off a perfect day with a hard fought 47-31 win over defending champions England at the World Netball series.
The result means that New Zealand, with four wins and one draw, were top qualifier for Sunday's semi finals and will meet fourth placed Jamaica. England will face the Proteas from South Africa in the other semi-final.
England, who were the only team with a 100 per cent record after the first day, were expected to provide tough opposition and duly delivered.
The Ferns led 13-10 after the first quarter, 18-14 at half-time but trailed 28-27 after a sensational third quarter where Jo Harten shot two six pointers (England had the power play), including one right on the buzzer. The home used their power play in the final quarter and that extra advantage was enough to ensure the victory, as they outscored their opponents 20 points to three in that six minute stretch.
On the evidence so far, the Ferns will start as favourites tomorrow but are taking nothing for granted.
