Those behind the scam are using adverts on popular websites, including Facebook, and sending emails telling people they can enter a competition and win up to $2000 of Bunnings vouchers.

Bunnings has confirmed they aren’t behind the ads and emails.

Some people have also reported seeing variations of the ads using the names of Kmart and JB Hi-fi.

Netsafe's digital project manager Chris Hails said the aim of these ads and emails was to harvest personal information from vulnerable internet users who fall for the prize hook and can then be sent other "spam".

"And secondly to possibly infect computers with drive-by download malware attack kits, which look for security holes on unprotected devices," Mr Hails said.

Consumer Affairs and Bunnings encourages customers to help eliminate these scams by reporting their experience at The Orb.

There are two other new scams to be aware of:

• Ministry for Primary Industries email scam

An email that appears to be from the Ministry contains a potentially malicious hyperlink.

The email says it has been sent by the Ministry for Primary Industries under the original email address marcdavidcox2009@gmail.com. It contains the text:

"Dear Diplomates [sic],

We are writing to let you know of progress and recent update within Ministry for Primary Industries, details has been attached via a secured message. Kindly CLICK HERE to view.

Ministry for Primary Industries

PO Box 2526

Wellington 6140

New Zealand."

If you receive the email, do not open it and do not click on the webpage hyperlink.

• Auckland Deaf Society scam

The Auckland Deaf Society has received reports of a man who calls himself Chris Rock contacting people on Trade Me and asking for their Paypal details.

He tells people he is deaf and works for the Auckland Deaf Society.

The Society does not know who he is and is warning people to ignore any requests from him. They have reported it to Trade Me and the police.
