Police have released a video resource on scamming and are encouraging older New Zealanders to take heed in order to protect themselves from losing money.
National Manager Crime Prevention, Superintendent Bruce Bird said older people can be particularly vulnerable to fall victim to fake promises and offers.
"Retirees may have spare capital for investment, they may be travelling more and booking holidays online, they may be new to online dating or buying goods online and this makes them vulnerable to online scams," said Mr Bird.
"Often they have cash on them and are more likely to be home during the day. This also makes them vulnerable to door-to-door scammers."
He encourages younger people to share the video with their relatives to help protect them.
