Skipper Daniel Vettori says that New Zealand lost out in their Test series with Australia because they failed to take their chances.
Vettori knew the Black Caps needed a full five good days of cricket to stand a chance of matching the Aussies, but they only managed sporadic bursts of form.
New Zealand started the second Test well when bowling in Hamilton, but failed to follow up with the bat and Ricky Ponting's men pulled away for a 176-run victory.
"We played really well at times, but to beat Australia you have to perform over five days," said Vettori.
"There were pockets there where we let ourselves down. Not supporting Ross Taylor in the first innings with the bat was a crucial bit because we had bowled so well to give ourselves a chance.
"We needed a sizeable lead to put pressure back on Australia and we couldn't manage that. Whether it's with the bat or the ball, it's how you seize those moments. And looking back on that first innings, to only get a 40-run lead was disappointing."
Australia won both the Chappell-Hadlee ODI series and the Test series, but Vettori felt New Zealand have had a reasonably successful summer.
After success at the Champions Trophy in South Africa, and back-to-back series wins over Pakistan and Bangladesh, Vettori said there were still plenty of positives to be taken from the summer.
"Losing two Test matches is tough but we'll try to look at everything in isolation," he said. "Going back to the Champions trophy and getting to the final there was an exceptionally good effort and winning the Test series against Pakistan was good.
"For me personally, there has been some really good things but as a Test match unit we've got a lot to work on."
Ponting agreed with the general consensus that New Zealand's Test frailties are down to not having a genuinely fast bowler, with Shane Bond retiring from Test cricket.
"Most teams around the world will have at least one of those guys that can do that (bowl around 150kph), and that will generally be the guy you go to when you need to strike," Ponting said.
"With New Zealand a lot of that striking comes back to Dan [Vettori]. I think [Tim] Southee's got the potential to become that sort of bowler so I think the more they stick with him the better he'll become.
"I know that New Zealand play the right way, and if they keep playing the way they are and keep playing positively and aggressively they'll put themselves in positions to win Test matches."
