New Zealand GDP for Q4 2017 came in weaker than estimated. NZD/USD fell about 30 pips ahead of and after the release but retraced that in the following hours. The pair's been quite resilient even amidst wobbly risk sentiment of late, mostly owing to U.S. dollar weakness. 0.72 - 0.74 range in play still. A successful break could see 200 pips in either direction.
