England captain Paul Collingwood conceded his team had produced a "very poor" performance in the second one-day international against New Zealand.
England lost by 10 wickets in Hamilton to trail 2-0 in the five-match series.
Collingwood said: "We're very disappointed, there are 11 blokes in the dressing-room who are devastated.
"We hit 85 from the first 15 overs but when the rain came it really knocked the stuffing out of us. I don't know why, but it was very poor from then."
For the second match running, England's innings was unhinged by three run-outs.
And after they had been bowled out for 158, three catches were dropped as New Zealand blasted their way to the winning target.
Commenting on the run-outs, Collingwood said: "I would have thought we would have learnt from the last game and I hold my hand up as I was involved with the first one.
606: DEBATE
"We are not getting totals on the board for the bowlers to defend and we have got to get that right pretty soon."
He refused to say there would have to be changes in team personnel for the third match on Friday, but added: "There will certainly be plenty of talking done.
"What it comes down to now is what kind of characters we have in that dressing-room.
"To bounce back from a defeat like this we've got to be honest with ourselves and see where we can improve."
By contrast, New Zealand opener Brendon McCullum was full of confidence after his sparkling unbeaten 80 containing five sixes gave his team a commanding lead in the series.
"We've been under pressure in the last couple of weeks and to come out and play like we did in the first game and again here was something pretty special," he enthused.
"I'm pretty sure now we hold all the cards so England are going to have to do something pretty special to steal back the momentum that we've created."
McCullum's innings was particularly inspirational after he revealed that his father had been rushed to hospital at the weekend following a heart scare.
"My old man had a heart attack on Saturday and I'd just like to say that my thoughts are with him and the performance I put up was a sign of the respect I have for him," he said.
"He's doing good now and hopefully it is just the wake up he needed. I knew about it before the match, but I didn't think about pulling out because he is stable.
"He's in hospital so I couldn't speak to him before the game, but I'm sure he'd have been watching if possible."
