The RBNZ has been talking the currency down for over a year and certainly won't discourage further falls. A negative trend in the currency has taken hold and the presumption that the economy will struggle this year, without a much lower currency, will keep it trending lower.
This number is quite a shock. This is a short-term negative for the currency and I'm surprised it hasn't fallen further.
The currency and rate futures markets are pricing in a rate hike by year-end and two by the middle of next year and this is why the euro has strengthened, especially against the yen.
