Kiwi is in a similar position (when compared to the AUDUSD). The rally to .6037 is either wave a or i within a larger rally sequence.
Wave b or ii may be complete at .5742 although risk remains that the pair drops below .5742 before a solid base is in place that will lead to a larger rally. As long as the NZDUSD holds above the short term support line, adoption of a bullish bias is warranted.
