The New Zealand dollar rose against the greenback on concern there are risks around Republican leaders looking to pass tax reform legislation and reach a budget deal with the Democrats before the end of the week to avoid a government shutdown.

The New Zealand dollar traded at US70.10c at 5pm from US69.89c in New York on Friday. The trade-weighted index rose to 73.98 from 73.85.

The US dollar - which gained overnight Friday on optimism US tax reforms will be enacted, including slashing the corporate rate to 21 per cent from 35 per cent - came under some pressure today on lingering uncertainty as Republics and Democrats must agree on a spending plan for the rest of the fiscal year before the end of Friday.

Otherwise, many federal government functions are frozen, and many federal employees are furloughed although essential activities - such as national security - continue.

The Washington Post reported that while Congress averted a partial shutdown earlier this month with a two-week deal that left spending constant and punted on all other policy questions, it's unclear if either side has interest in another short-term deal.


The kiwi saw "a bit of a grind higher" in light trading, said ANZ senior economist Phil Borkin. "It may be the government shutdown possibility in the US looming in the background. That might be holding back sentiment about the tax package."

He noted, however, the holiday season may already be sidelining some Kiwi dollar investors or they may be waiting for more data later in the week, like the third-quarter gross domestic product data on Thursday, which is expected to show growth slowed to 0.6 per cent in the quarter for an annual pace of 2.4 per cent.

The year's final dairy auction and the ANZ business confidence survey will also garner interest, said Borkin.

The Kiwi dollar traded a 52.56p versus 52.72p in New York on Friday as Prime Minister Theresa May prepares to present her plan for the Brexit transition period.

It was at 59.58 euro cents versus 59.53 euro cents and at 78.98 yen from 78.78 yen on Friday in New York. It was at A91.49c from A91.39c and traded at 4.6337 yuan from 4.6235 yuan.

New Zealand's two-year swap rate rose 1 basis points to 2.18 per cent and the 10-year swaps rose 2 basis points to 3.09 per cent.
