Shane Solly, portfolio manager with Harbour Asset Management, said there was a bit of nervousness around what happens with the central banks' discussions.
"Once we get the communications out of the meeting things will be clearer. Inflation is still very high and I don't see the central banks cutting interest rates any time soon."
US Federal Reserve chair Jerome Powell was making a keynote speech overnight.
The NZ dollar was weaker at 89c against the Australian after being above 90c for the past four months.
