Bullish persistence above 0.6550 (the depicted support) was necessary to keep the price moving towards higher bullish targets.
In February and March, signs of bearish rejection (triple-top reversal pattern) were expressed around the price level of 0.6750 until April when a bullish breakout above 0.6750 and 0.6860 was executed.
Later on May 6, daily candlestick closure below the 0.6850 level enhanced a quick bearish movement towards 0.6750 where bullish rejection was expected to be applied. However, obvious bearish closure below 0.6750 was achieved on May 24.
On May 30, obvious bullish rejection was expressed around the price level of 0.6675 (the lower limit of the depicted channel). That's why, the recent bullish breakout is taking place above 0.6860.
As long as the NZD/USD pair kept trading above 0.6860, further bullish advancement was expected towards the price zone around 0.7200 (the upper limit of the depicted channel).
Price action should be watched around the price zone of 0.7150 - 0.7200 (the upper limit of the depicted channel) for a valid SELL entry (A recent Head and Shoulders reversal pattern is being expressed on the chart).
T/P levels should be located at 0.6970, 0.6900 and 0.6850.
On the other hand, the price zone between 0.6760 - 0.6860 constitutes a significant support zone to offer bullish rejection and a valid BUY entry if bearish pullback persists below 0.7000.
