A fresh wave of USD buying sends NZD/USD to new cycle lows, at 0.8072 at the time of writing. No major US or New Zealand related headline has hit the wires. The kiwi is just suffering more than others at the moment from a wave of USD buying.
0.8050 was the low point in February. If the pair loses this one as well, it will be trading at the lowest level in one year: it traded around these areas back in September 2013.
Support for the kiwi awaits at 0.8050, followed by the very round number of 0.80. Resistance is at 0.81, followed by 0.8150.
Earlier, a peer commodity currency, the Canadian dollar, was hit by weaker than expected retail sales. The Aussie managed to recover on better than expected Chinese manufacturing PMI but later resumed its falls.
Here is how it looks on the weekly chart:
