"We're looking at the changing the style of play we have and it's going to take some time for us to become comfortable doing that, but I was pleased with the way we controlled possession again,'' coach Tony Reading said.
"We had some good opportunities in the first half but went in to the break scoreless but gradually we asserted our dominance on the game and scored the two goals.''
New Zealand beat Italy 1-0 the last time they met at the 2010 Cyprus Cup and today's result is another encouraging sign of the side's development.
They now have the luxury of two rest days before facing England in their final Group A match.
"The extra rest day is welcomed as we prepare for England,'' Readings said "We watched them come back from 2-1 down against Italy on day one to win 4-2.''
The Football Ferns were beaten 2-1 by England at the 2011 Women's World Cup in Germany and last year lost 1-0 at the Olympics against Great Britain - a squad which featured 16 English players and two Scots.
"We know each very well so I can see the match being a tactical battle but, more importantly, there is something riding on it which gives us more tournament experience and adds a bit of pressure on our players to finish top of the group'' Readings said.
