The lethal opening combo produced an exhibition of belligerent hitting, clearing the short boundaries on offer at will with some lusty hitting. While Guptill got to his half ton in just 20 balls, with 5 towering sixes and 3 boundaries, Munro played a whirlwind 21-ball 46 run knock.
Guptill was the first to be dismissed by leg spinner Adil Rashid. All-rounder Colin Grandhomme departed early following which Munro staged a blistering partnership with Tim Seifert. Munro eventually fell to Sam Curran just four short of his half ton.
Wicket-keeper batsman Tim Seifert provided the late flourish with a quick-fire 39 cameo off just 16 balls.
The five match T20I series is currently tied at 2-2 and it all to play for in the series decider in Eden Park at Auckland.
