The New Zealand dollar has slipped from a three-year-high last week, but is expected to hover around the 80 US cents mark.
The kiwi on Tuesday was trading at 79.98c - just below the 80.36c reached on Monday morning.
Westpac market strategist Imre Speizer says the drop was due to a dip in commodity prices and the US equity market.
Mr Speizer says commodities and equities are the biggest factors in the kiwi's future.
