The New Zealand dollar got a lift when the ANZ business outlook survey for December showed a net 24.1 per cent of firms surveyed expect general business conditions to deteriorate in the coming 12 months versus 37.1 per cent in November.
Business confidence has plunged since the Labour-led government was formed in October last year and implemented a series of policies that have impacted business.
These include lifting the minimum wage, changing immigration settings, implementing fuel taxes and proposing changes to the current employment law.
The kiwi had been range trading ahead of the outcome of the US Federal Reserve's last policy meeting of the year and domestic economic growth data for the third quarter, both due on Thursday.
"The market was short kiwi and the sentiment survey has upset the apple cart slightly because it was better than expected," said Tim Kelleher, head of institutional foreign exchange sales at ASB Bank. When investors are short kiwi it means they are betting it will fall further. Some of that positioning was pared back after the confidence survey.
Kelleher said, however, the main event this week will be the Fed's statement and forecasts.
While the Fed is widely expected to lift rates at this week's meeting, investors will be waiting to see if the Fed eases up on its plans for 2019.
According to its latest projections in September, the median view among policymakers was for three rate hikes in 2019. Recent commentary from Fed officials, including Chair Jerome Powell, has pointed to a softer stance. In late November Powell said interest rates were "just below" what the Fed considered neutral.
"The risk is that we get a dovish hike," said Kelleher, with the Fed signaling fewer rate hikes for 2019.
The Fed will be followed by third quarter GDP data, with the market expecting a lift of 0.6 percent quarter-on-quarter according to a Bloomberg poll.
