New Zealand, the 2000 edition champions, have already made their intentions clear by notching up two consecutive wins - against Pakistan and South Africa.
Five-time champions Australia are also a strong title contender what is their batsmen are yet to fire in unison in the tournament.
Against Pakistan in their opener, Australian batters struggled to post just 188 before their bowlers saved the day, skittling Pakistan for just 84 runs to win the match by 91 runs.
The Australians would not be treated so kindly on Tuesday by their neighbours as New Zealand looked the side to beat in the tournament with solid performances both with the bat and ball.
Captain Suzie Bates has been in menacing form with a 73 against South Africa and 65 not out against Pakistan. Her colleague Sophie Devine cracked 145 to set her side's easy win over South Africa.
Their bowlers have also been in brilliant form, skittling out South Africa for just 170 and Pakistan for 104. Sian Ruck took four wickets in the match against South Africa while Rachael Candy grabbed five wickets against Pakistan.
Going by current form, New Zealand are a better batting side as the Australians have not exactly clicked as a team.
