Consider four factors:
(1) The price of commodity (up or down?)
(2) The devaluation of US dollars (NZ dollars up)
(3) The adjustment of reserve by different countries (But no componet on NZ dollars, NZ dollars up a little bit)
(4) The trade deficit of NZ (NZ dollars down)
Overall: Those who buy NZ dollars at a high level have good opportunity to get back their money, but forseen profit will not be much.
