The New Zealand dollar was little changed as investors digest efforts by the People's Bank of China to arrest the slide in the yuan and Federal Reserve chair Jerome Powell's latest speech.
The kiwi traded at 66.87 US cents at 5pm in Wellington from 66.82 cents at 8am and 66.90 cents on Friday in New York. The trade-weighted index was at 72.20 from 72.22 last week.
The yuan hit a two-and-a-half-week high against the US dollar on Monday when PBOC set the day's midpoint at a stronger-than-expected level after reintroducing the so-called counter-cyclical measure to help stabilise the currency. The tool essentially reasserts a heavier hand in setting the currency's value, something the PBOC had eased back on, leading to a 10 percent decline in the yuan against the greenback between April and mid-August.
The move comes after US President Donald Trump accused China of weakening the yuan to help soften the impact of trade tariffs, and was seen as a bid to stem some of those concerns.
News that Powell reiterated that US interest rate increases are likely to be gradual Friday at the annual central bankers' forum in Jackson Hole, Wyoming also helped improve risk appetite.
