The New Zealand dollar dipped then bounced back on a so called "relief rally" after the news of a infant formula contamination threat broke in volatile trading.
Police are appealing for the public's help following a threat to contaminate infant formula and other formula in an apparent protest over the use of 1080 poison in pest control.
The New Zealand dollar was weakening as talk of a big announcement about the dairy industry - by far the country's biggest export - spread through the financial markets.
In the minutes preceding the 3.45pm announcement, the Kiwi went from US73.40c to US72.80c but rebounded to US73.10c when the announcement came out.
By 4.20 pm it had eased back to US72.90c.
