New Zealand 119 for 2 (Bates 52, A Kerr 33*) beat Sri Lanka 118 for 6 (Hasini 33, Tahuhu 4-21) by eight wickets
Bates combined with Bernadine Bezuidenhout to add 48 for the opening wicket. She was the steady partner in their partnership but attacked in the 59-run second-wicket alliance with Amelia Kerr. In the process, Bates scored her 26th half-century in T20Is. She used her feet to the spinners to put them off and was innovative in her strokeplay – using the scoop and paddle to good effect.
Inoka Ranaweera managed to see the back of Bates when she had her holing out to long-on for 52 off 53 balls, but Kerr and Sophie Devine finished the job without fuss.
Earlier, after being put in, Sri Lanka were jolted early when captain Chamari Athapaththu was run-out in the third over. She turned an Eden Carson delivery towards the left of the non-striker, Vishmi Gunaratne, and set off for a non-existent run.
Tahuhu then struck twice in her opening over – she first had Gunaratne chopping on when attempting a drive before trapping Kavisha Dilhari lbw two balls later.
Anushka Sanjeewani and Nilakshi de Silva propelled Sri Lanka past 100, with the two taking 13 off a Leigh Kasperek over, but the total was never going to be enough.
