Not the most informative warning. No mention of when or how severe likely!

FWIW the earthquake occurred at 12:24:51 this afternoon our time, and any tsunami will take 12 - 13 hours or so to reach northern NZ. So a few hours yet before need to worry too much. More info here if interested ww.tsunami.gov. Prelim est 0.3m - 1m tsunami in NZ.

Travel times below from https://www.ncei.noaa.gov/maps/ttt_coastal_locations/
CD could easily have got this info with a few minutes work.

List of times from Stuff at this link

Also, @DS248, your image link just comes up broken for me - which may well be a "me" issue as I'm behind a corporate proxy currently.

The TLDR for NZ is

"don't go to the beach at Midnight" ... in the middle of winter .....

I thought the message was clear, not sure what the OP was talking about. @wellygary is right: don't go to the beach, just that.

And yet, someone posted this on that other network, showing that some didn't read the message at all:

Yip the warning message, and TBH most of the official comms have been very unclear, and IMHO a bit crap.

from Civil Defence,

"The first tsunami activity causing these strong currents and surges may reach New Zealand in the areas around Lottin Point at approximately 11.59pm NZST tonight.

Strong and unusual currents and unpredictable surges will continue for several hours and the threat must be regarded as real until this Advisory is cancelled."

How close to the coast are your phones?

Mind you, with ~7 hours until first arrival, maybe everyone should get it; eg, some people currently inland may intend heading to the coast later on ...??

Calls I make and receive appear to be about 50:50 Wifi Calling or normal mobile network depending on where I am etc. I'm at home (wifi?) & got the message. Presumably would only be an issue if solely using Wifi Calling?

I got the alert.

However, I couldn't bear the noise and so decided to confirm the prompt (I am now trying to remember) and assumed I could retrieve the message without the sound.

I made a mistake, and I cannot find it, to re-read it.

I'll be ready next time to lower the volume to zero.

Didn't get the alert.

Live in Paeroa though, so assume that's why (though, if there's a decent surge in the firth of Thames, it'll come up the river).

I get it double on my iPhone due to dual SIM, but I also got it another two times because I applied the iOS 18.6 update, and then another two times as I put it in aeroplane mode to see if I could convince it to reconnect my One NZ SIM to the tower...

I don't know if it's something funky with the phone, or an interaction with One & the RCG tower, but I noticed this last time an emergency alert went out (Abilities Group fire IIRC), the OneNZ signal would just die and revert to solely to WiFi Calling, triggering a reconnect would work for a few minutes (long enough to get the alert again anyway) and then be dropped after a short period of time.

The Warehouse Mobile SIM (2degrees) which normally connects to the same tower is fine (but can't be 100% sure because there is a 2degrees tower in the other direction that was close enough to provide signal most of the time before the RCG tower went online).

Assuming you are using Android phone:

Got the alert on my Vodafone/One phone and my boy got it on his 2degrees one a minute later, even we're not really near the coastline. Is it done by serving cellsite?

On my S23 FE the sound stopped as soon as I touched the screen. Message stayed displayed until I hit OK.
