You may have received an email advising you to receive or redeem a free prize or receive an outstanding refund. The prizes include Apple products, New World vouchers and smartphones. From what we have gathered, the email is usually signed off by "Vicky Hannson", Consumer Analyst.
We have also been informed of customers receiving call s from someone claiming to be from Microsoft Helpdesk. This is a well known scam where the caller claims to be reporting a problem with your computer and request remote access.
If in doubt, just hang up and contact CERT NZ.
