The White Ferns remain top of the table at the women's Cricket World Cup heading into their second group game on Wednesday night.
New Zealand sit tied on two points with India and South Africa who also enjoyed opening victories to the tournament. The White Ferns opened their campaign overnight Sunday with a comfortable nine-wicket victory over Sri Lanka.
Transtasman rivals Australia play their first game against West Indies tonight while hosts England look to bounce back against Pakistan on Tuesday following a first-up defeat to India.
The White Ferns made a near perfect start to the tournament.
Chamari Polgampala (49) and Chamari Athapaththu (53) gave Sri Lanka an ideal foundation to kick on at 141 for one with 15 overs remaining, but once the latter fell a flurry of wickets followed.
