Most of the weak NZD shorts will have been culled by now in what has been an extreme market reaction to what was basically an expected event. Recent market momentum has been poor and I find it unlikely that NZD/USD will simply keep going in a straight line higher in the short-term at least.
There is solid technical resistance near .8690/95 (recent highs plus a 76.4% retracement) and bears can try selling there if an hourly top forms, with relatively tight stops as always.
