New Zealand data and the thin evening book
Some of the most dramatic New Zealand releases land when Europe is asleep and New York is winding down. Employment, inflation, and the Reserve Bank's decisions arrive during the Wellington morning, which falls in the New York late afternoon or evening depending on the season.
NZDUSD reacts quickly, and so do the crosses. But the book is thin. A surprise can move the pair 40 or 50 pips in seconds, with spreads of 5 to 10 pips.
The moves also tend to extend. In a market with few participants, a push in one direction isn't absorbed quickly. A 30 pip jump can become 60 over the following ten minutes before any reversal.
Most brokers' calendar default settings show these events in server time, which is often not the local time of the trader. The result is a lot of surprise entries into the release.
Marking NZ and Australian releases on a separate calendar with a notification helps if the plan is to avoid them, or to trade them with open eyes.
During a New Zealand release, how far do NZDUSD spreads stretch on the account used here?

Re: New Zealand data and the thin evening book
I got caught by this once with an RBNZ decision that I thought was the following evening because my platform showed server time. I had a small AUDNZD position open and the cross jumped further in a few seconds than it normally moves in a whole session. Not a disaster, but the slippage on the stop was enough to make me take the calendar seriously.
On my account NZDUSD normally sits under a pip during the European session. Around the employment and inflation releases I have seen it go out to 7 or 8 pips for close to a minute, and on one rate decision it touched 12 before settling. The crosses are worse, and NZDJPY can be almost untradable for the first couple of minutes.
What I do now is set phone alerts in my own time zone for anything from New Zealand or Australia, and I flatten anything with NZD in it twenty minutes before. If I want to trade the reaction, I wait until the spread has returned to normal for at least two minutes.

Re: New Zealand data and the thin evening book
New Zealand data and central bank announcements arrive in the Asia-Pacific early morning, when most of the world is asleep. The Reserve Bank of New Zealand announces decisions at 2pm local time, which is the middle of the night in Europe and the previous evening in the United States.
NZDUSD and NZD crosses can move forty or fifty pips in seconds, with very little liquidity behind the move. The market is small, so a decision that surprises even slightly triggers a reaction well beyond what the data would justify.
Spreads balloon. Order books thin out. Fills during the first minute are poor, and quotes can freeze.
For anyone trading from a distant time zone, the risk is being caught by an event without paying attention. A position left open overnight, or a bot running through the night, may encounter the move at its worst.
Quick reversals are common. Much of the spike gets retraced as the Asian session continues and other participants step in.
The sensible use is awareness: know the RBNZ schedule and avoid having positions or automation active around it, unless the strategy is built for it.
There's another aspect of the New Zealand market worth noting: the size of the currency's market relative to others. Daily turnover in NZD is a small fraction of that in EUR or JPY. That means even moderate orders can cause visible moves, and the effect on crosses with AUD, CAD, and JPY is magnified by thin liquidity in the whole region at that hour.
A few traders do specialize in these events, using small size and wide stops, accepting that fills will be poor but the move is large. For most, the better choice is to stay flat.
A calendar alert for RBNZ decisions, set the day before, gives time to flatten positions and cancel pending orders. The decision times are fixed in the central bank's annual schedule, and the dates are published far in advance.
Anyone running automated systems overnight should check whether the bot has a news filter that covers events outside its home session.
