Two men travelling from Auckland managed to pass lockdown restrictions to get into Hamilton to play at a SkyCity casino.
But their luck ran out when staff there recognised where the men had come from and they were asked to leave immediately.
The incident happened on Thursday night - a day after Auckland was put into alert level 3 lockdown when a family of four tested positive for Covid-19 through community transmission.
Police confirmed authorities had been advised by staff at SkyCity Hamilton that two men from Auckland had visited the casino on Thursday.
