The NZDUSD has declined impulsively (5 waves) since its 2008 high and that decline was followed by a 3 wave rally (from the November low). The decline from .6090 is now in 5 waves and the risk of a sharp advance back to at least .5454 in a small second wave is high. The close above the trendline from early January as well as divergence with RSI on the daily favors bulls.
