The kiwi was trading at 68.97 US cents at 5pm in Wellington from 67.78 at 8am and at 95.07 Australian cents from 95.25 cents this morning
"It was an Aussie strength story," says Kiwibank dealer Mike Shirley, adding that the kiwi fell from 95.60 cents immediately before the RBA statement.
The RBA kept its cash rate unchanged at 1.5 per cent, which was no surprise to anybody.
"Where the surprise came from was that, leading into the announcement, the market was pricing in a reasonably good chance of a rate cut from the RBA over the course of this year," Shirley says.
This morning, market pricing had suggested a one-in-three chance of such a cut this year.
"The language of the statement certainly wasn't supportive of that," he says.
The fact the RBA is expecting the underlying inflation rate to reach 2.25 per cent by 2020 "is certainly not language that suggests a rate cut is imminent."
The central bank did acknowledge weakness in recent data, saying that "as is the case globally, some downside risks have increased. GDP growth in the September quarter was weaker than expected."
Data released earlier today in Australia showed December retail sales fell 0.4 per cent in seasonally adjusted terms, defying expectations for a steady result.

The trade-weighted index rose to 74.36 points from 74.20.
The two-year swap rate fell to 1.8980 per cent from 1.9082 yesterday; the 10-year swap rate is at 2.5030 per cent from 2.5075.
