The New Zealand dollar today jumped to its highest exchange rate against the greenback since it was floated in March 1985, and reached US83.18c just after 3pm.
Its previous post-float high of US83.01c was notched up last Friday night.
Reuters reported the outperforming kiwi had pushed the Australian dollar exchange rate against the NZ dollar down to $NZ1.2906, off this week's high around $NZ1.3045, but the aussie had also powered to 26-year highs against the pound sterling and hit 3-week peaks against the US dollar on Thursday.
Overnight the NZ dollar also powered to a new post-float high against the British currency, and by 3pm was trading around 51.60p.
