Scam Prevention Working Group

Working together to reduce scam calls and SMS.

What it is

The original purpose of the Scam Prevention Working Group was to develop an industry code of practice for Network Operators to identify, verify and take action on scam calls to landlines and mobile phones. 

Subsequent to the development of the code, the Working Party meets quarterly to monitor implementation of the code and developments in scam call and SMS prevention technology as well as to extend cooperation regarding scam call and SMS processes to agencies outside of the telecommunications industry to improve outcomes for consumers.


New Zealand, like many other countries, is targeted by off-shore based phone scammers calling or texting national landline and mobile users.

The scammers attempt to persuade anyone who answers their call, or receives their text, to cooperate in some way.

Their objective is to extract funds from the recipient by deception, and transfer it to the scammer’s bank account.
