London, June 30: Kane Williamson says New Zealand cannot afford to dwell on their 86-run Cricket World Cup thrashing by Australia ahead of a potentially crucial clash with England.
The Black Caps would have been guaranteed a place in the semi-finals if they had beaten their trans-Tasman rivals at Lord's on Saturday, but crumbled to 157 all out in reply to 243-9.
Trent Boult (4-51) made history by becoming the first man from New Zealand to take a World Cup hat-trick, but Mitchell Starc starred with 5-26 after Usman Khawaja (88) and Alex Carey (71) gave the Australia players a decent total to defend.
New Zealand are three points ahead of fifth-placed England - who have a game in hand against India on Sunday (June 30) - and Williamson says the 2015 runners-up must put a heavy defeat in London behind them, with an encounter against the hosts to come in their last group match on Wednesday (July 3).
The Black Caps captain said: "It wasn't to be today, and we have to pick ourselves up and move on. I guess we have to look at the surface (for the showdown with England at Chester-le-Street) and make the right decisions.
"We have an extra day off, and it would be nice to freshen up a little bit. The wickets haven't been what a lot of people thought - they are perhaps tired."
Williamson, his side's top scorer with 40, added: "It was a fairly challenging surface. If you were willing to hit the wicket hard, there was something in it, and there was some up-and-down bounce as well.
"Lots of spin as well, and a lot of credit for the way they rebuilt their innings and got to a competitive total. Obviously, we were trying to get the match-ups.
"I probably bowled a bit more than I should have, with the left-handers in the middle. Throughout the innings, we thought we had them under control, but Carey took the game away with a brilliant partnership.
"Some big lads hit the wicket hard and got something out of it. What we needed was one major 100-plus partnership where we could soak up some pressure and turn the momentum our way."
