"Trump firing the FBI director has created uncertainty enough to say, will he enact the policies, the tax reform and infrastructure spend, and the market's just losing a little bit of faith in the Trump reflation trade at the moment," said Graham Parlane, private client manager at OMF. "There's a little more potential for the kiwi to go a bit higher on the week - there's been reasonably negative sentiment around the kiwi for a while now as it loses its yield advantage, but with this US dollar turning turtle, that sentiment could easily unwind."

Minutes to the Fed's last policy review are due on Thursday, and the central bank is still widely expected to raise the federal funds rate at next month's meeting.
