New Zealand releases most of its important data early in the Asia-Pacific day, often around 21:45–22:45 UTC. At that time, global FX liquidity is close to its daily low.
What that means for NZDUSD:
Reactions to CPI, employment or RBNZ decisions can be sharp because few participants are active.
Spreads may widen for several minutes, not just seconds.
Moves sometimes partly reverse when Sydney and later Tokyo add liquidity.
Practical approaches:
Avoid holding tight stops in NZD pairs through these releases.
Use the post-release range as a reference for the Asian session.
Compare NZDUSD with AUDNZD: if both move, the reaction is NZD-specific.
For European traders, these releases fall late in the evening, which makes it tempting to trade them tired. Deciding in advance whether you trade them at all is part of the plan.
Do you trade NZD releases live, or wait for the Asian session to settle?
New Zealand puts out most of its data at 10:45 local. Since the country moved to daylight time in late September that is 21:45 UTC, only 45 minutes after the New York rollover while the US is still on summer time.
Once the US clocks go back on 1 November, rollover moves to 22:00 UTC and the release lands just after it. NZDUSD spreads are often still two or three pips wide from rollover at that point.
I stopped trading the print live a while ago. What I do instead is note the high and low of the first 30 minutes after release and treat the midpoint as a magnet once Tokyo opens.
On the CPI nights I logged, price came back to that midpoint before 01:00 UTC more often than not. It fits the partial reversal described here.
The AUDNZD check is a good one, and I add a second step. If AUDNZD barely moves while NZDUSD jumps, the move is broader than kiwi, usually the dollar or the whole Antipodean block, and I size it as that.
Does anyone hold through RBNZ decisions with a wide stop? Flat has always looked like the only sane option to me.
