The currency did appreciate after the New Zealand Institute of Economic Research's quarterly survey of business opinion showed net pessimists fell to 18 per cent in the December quarter from 28 per cent three months earlier.
"But we're talking about 20 points on the entire day so it hardly set the world on fire," says Mike Shirley, a dealer at Kiwibank.
The next potential market mover is the outcome of the latest GlobalDairyTrade auction due overnight New Zealand time.
"That may add a little bit of local flavour to currency moves," Shirley says.
At the last auction, the first for 2019, the headline index rose 2.8 per cent, the third consecutive climb, amid a drop in supply. NZX dairy futures are indicating a further rise is likely.
But the event with the most market-moving potential is definitely the Brexit vote, Shirley says.
"All and sundry are expecting that vote to fail and the question is by how much it fails – it looks like it will be by the biggest margin in a century. It's not a record you would particularly want to hold," he says.
But whatever the outcome, it will only raise a whole host of new questions, such as whether there will be vote of no confidence in May's leadership and what happens next with Brexit.
"This is just the initial domino that's going to be pushed," Shirley says.
Bloomberg is reporting that at least 70 of May's Conservative Party members, as well as sometime allies in the Democratic Unionist Party, have pledged publicly to join the opposition Labour Party in voting down her Brexit plan.
That could translate into a margin of defeat of more than 150 votes, the largest in more than a century. Even if some abstain, a defeat by more than 100 votes would be the worst since 1924.
If the margin of defeat turns out to be less than 60 votes, EU officials may look at fresh ways of making the agreement more palatable, Bloomberg said.
