The New Zealand dollar hit a month-high as investors were disappointed US president-elect Donald Trump didn't provide much detail on his spending programme in his first press conference, prompting a sell-off in the greenback.
The kiwi rose as high as 70.87 US cents, trading at 70.60 US cents as at 8am in Wellington from 69.97 cents yesterday. The trade-weighted index advanced to 77.88 from 77.45.
The US dollar index, a measure of the greenback against a basket of currencies, fell 0.5 per cent after Trump's hour-long press conference focused on reports of Russian interference in last year's US presidential election and an intelligence report that Russia holds compromising information about the president-elect.
Investors were hoping for more details about Trump's planned spending on infrastructure and tax reform, which took a back seat in the briefing.
"The USD index was trading a fairly steady path higher overnight, before a bout of volatility as the US president-elect gave a scheduled press conference early this morning," Bank of New Zealand senior market strategist Kymberly Martin said in a note.
"He covered many topics, but gave little detail on any fiscal stimulus plans. After his free-ranging comments the USD has fallen."
