The kiwi was at 65.46 US cents at 8am in Wellington, from 65.38 cents at the New York close and 66.44 cents at 5pm on Friday.
The New Zealand dollar fell after the Federal Reserve raised interest rates for the first time in nearly a decade and kept its outlook for future hikes on track.
The kiwi was trading at 67.66 US cents at 8:30am in Wellington, from 67.79 cents immediately before the Fed's decision was
released at 8am, and from 67.65 cents at 5pm yesterday.
It dropped as low as 67.10 US cents after the announcement. The trade-weighted index was at 73.60 at 8:30am, from 73.69 at 8am, and 73.55 yesterday.
The Federal Reserve's policy-setting committee raised interest rates in the world's largest economy by a quarter percentage point to between 0.25 percent and 0.5 percent in a unanimous decision, and highlighted that the rate hike was a tentative beginning to a gradual tightening cycle.
The Fed's economic projections were largely unchanged from its September forecasts, with the so-called "dot plot" path for interest rates continuing to signal it planned to raise rates four times next year to take the benchmark 1 percentage point higher.
