For further context on this story which is not really given as this is a local news outlet a lot (maybe 50%+ ?) of all fuel stations in NZ are completely unmanned. You authenticate your card or phone at a terminal, select the pump and then that pump is unlocked and you fill up. There are no attendants to assist you or accept payment.
If it were London, they would be card skimmed and gas siphoned blind. I guess the isolated and smaller population of NZ leads to inherently fewer problems and perhaps more trust.
