Bowling coach Shane Bond said they need to improve their batting in particular ahead of their first World Cup match against England on Sunday morning (NZT). They play Australia in their final warm-up game tomorrow night.
"We just didn't get quite enough contributions around Brendon today,'' Bond said. "We didn't play anywhere near our best and we still got close to a win so there are a few areas for us to tidy up.''
Southee expects scores like what they posted will be competitive in the tournament.
"They're not going to be big scores. I think with the nature of the slowness of the wickets, whether they'll be the same in the actual tournament we'll have to wait and see, but I think around those 150 scores they'll be competitive and defendable.''
He says they will take plenty out of the game and realise they have to build partnerships.
"The benefit of it happening in a warm up game I think we can learn from it. And I think that's what kills you in Twenty20 cricket, when you lose wickets in clumps and it's hard to start obviously.''
