As you can see on the daily timeframe there is a double top pattern formed. Price already broken below the support with a big bearish engulfing candle. This upwards movement could be only a retracement before further drop in this pair.
Price spent several weeks consolidating inside 1.6820-1.6660 area which also looks like a flag pattern to me.
Sell EURNZD 1.6760
Stop loss 1.6820
Take profit 1.6400 (6R)
Use only 1-2% risk
Good luck
