An new scam is conning people to divulge their bank pins under the premise of winning a grocery hamper.
The victims are people who have had their wallets or purses stolen a few days earlier and are asked to think of a four-digit number to receive a hamper full of groceries.
North Shore police Constable Damian Albert said because the callers weren't outright asking for a pin, it was easy to be tricked.
"A lot of people, if asked to think of a four-digit number, would give the same number they use as their pin, because it's easy to remember.
"It's possible that the offenders have used other business names with similar scenarios, and we'd like to hear from anyone who has had their cards recently stolen on the North Shore and has then experienced this type of phone call."
