For those who live in NZ, how often does One and Three cut into programming for breaking news as it did last Friday. I'd assume it's quite rare.
According to Wikipedia, the last three times a 1 News special has aired outside the Gov't Budget, were the 2016 Kaikoura Earthquake, 2016 U.S. Election and the 2014 Sydney hostage crisis. However, I'm not sure when that list was last updated, and considering that the list does not yet include recent events in Christchurch, it would be reasonable to take the list with a pinch of salt.
The page for Newshub does not have any list of such broadcasts.

Barely ever. It only normally happens if it effects New Zealanders on a national scale so like Jacinda Adern fronting after giving birth or if it effects a certain city majorly so an Earthquake or the Attack last week or if a State of Emergency is placed, in turn with TVNZ & Three been a Civil Defence Broadcaster they need to be on air to give details to locals.
Does NZ have any regional broadcasters in Christchurch. IIRC they don't have regions on the main channels but sure there are some local channels - there was the one who had the 2004 ITV regions look.
