Auckland: New Zealand today became the first team to enter the Cricket World Cup quarterfinals, clinching a nerve-wrecking one-wicket triumph over four-time champions Australia after dismissing them for their second lowest tournament total in a pool A thriller here today.

In a low-scoring match that went right down to the wire, the nervous Kiwis huffed and puffed to victory after man of the match pacer Trent Boult's career-best five-wicket haul had helped bowl out the Aussies for 151 in 32.2 overs at a packed Eden Park.
