Initially I thought the same as you as long position is the way to go. However it is only short term.
1) NZD/USD spiked up due to disappointing US inflation data at 8:30pm. I was saying yesterday that it is trying to break 0.729X for the third time. Before that the market has started to position itself and priced in already around 0.729. The disappointing US inflation data was what it needs to push it over to 0.73X.
2) Being last day of the week many traders will want to carry trade to receive swap points over the weekend. So they long it thus demand is higher.
3) RBNZ has said several times NZD should weaken not strengthen. The last statement made was about 48 hours ago. This is the indicator to me I should short not long. Being Friday already I want to position for next week and not for a few hours of trading time left.
4) RBA has also said a strong AUD is not good at this moment. AUD/USD is correlated to NZD/USD. My stucked AUD/USD short position is recovering day by day. THIS IS WHY I AM CONFIDENT. The trend will be down as both currency pairs correct southwards. RBA has also expressed that it may intervene if it deem necessary. My number 1 rule is never to go against central bank policy.
NZD/USD closing price was 0.732X and if you put in a buy on Monday you are already too late because limited furthur upside. It will retrace below 0.73 at some point. 0.73 is the physcological barrier for up or down.
If my strategy is correct. Upon open NZD/USD may gap down and may hit my buy limit order.
This analysis report may seem short but it is through many hours of reading, research and staring at charts!
