The New Zealand dollar has risen as global investors await interest rates rises here in coming months and fears lessen about Greece's debt problems.
At 11.15am on Monday, the kiwi was almost 73 US cents, after rising to 73.3 US cents over the weekend - its highest level in three months.
BNZ currency strategist Mike Jones says the currency has gained about 2 cents since the Reserve Bank signalled on Thursday that the Official Cash Rate would rise soon on the back of the economic recovery. The OCR has been 2.5% since 30 April, 2009.
Mr Jones says the kiwi has also risen against the Australian dollar, which has been hit by China tightening monetary policy.
Economic and debt concerns in Europe also made New Zealand an attractive place to invest.
At 12.15pm on Monday, the New Zealand dollar was trading at 72.84 US cents, 78.68 Australian cents, 47.63 pence, 68.51 yen and 0.5480 euro. The Trade Weighted Index was at 67.93.
