Nerves got to New Zealand in their below-par performances against Australia, according to bowling coach Shane Jurgensen.
The batsmen let the side down in the third and final ODI in the Chappell Hadlee series in Australia last week, but it was the bowlers, and by extension the lack of support from the field, which was the main issue in games one and two in Sydney and Canberra, as New Zealand were swamped 3-0.
In Canberra, New Zealand were forced to chase Australia's second-highest score ever at home in an ODI, 378 for five.
But when New Zealand reflect on the series, they'll realise game one at the Sydney Cricket Ground was a major lost opportunity.
They had the hosts 92 for four in the 20th over, but could not seal the deal, as captain Steve Smith rocketed away to a ground record 164.
