There can only be one winner of this five-game series, which concludes in Mt Maunganui on Tuesday, but Sri Lanka will fancy their chances of squaring it, after Thursday's eight-wicket win.
Indeed, they did well in vastly different circumstances yesterday.
Take out Martin Guptill striking three sixes in four balls off lively Dushmantha Chameera's second over, which cost 26, and one over of dross at the end from legspinner Jeff Vandersay, which went for 15, and the Sri Lankans did a decent job.
The ball held up enough to make the slower delivery an ace, but it's easy to imagine players' were finding it hard to switch on.
There was time for left arm spinner Milinda Siriwardana to bowl the worst delivery of the summer to Henry Nicholls. It stuck in his hand, bounced in front of the non-striker and bobbled down beside the pitch towards first slip.
New Zealand coach Mike Hesson admitted had there been a full match yesterday it may have offered Sri Lanka their most appropriate conditions of the series.
"Today was a good opportunity for them (Sri Lanka) on a really used surface. They would have been the most Sri Lankan conditions we'd have faced today and that would have been a challenge."
Captain Brendon McCullum sat the game out, still recovering from his injured back, while more expert information is being sought on the foot injury which hampered Tim Southee in Thursday's match.
Southee hurt his left foot in his first over of that game.
He was struck on the left foot by Australian quick Mitchell Starc at Brisbane in November. He had been untroubled since then, but the injury has flared up.
"Until we get a full picture and get someone skilled to look at them we're a little bit up in air," Hesson said. "Everyone seems to be on holiday. We've been able to get some scans done and we're hopeful he'll have part (to play) in the near future."
Trent Boult is back in the New Zealand squad for the fifth game.
