Doctors and specialists have been scamming New Zealand's biggest health insurer, Southern Cross, which has just announced new measures in an attempt to save millions of dollars.
Stefan Azzopardi, the society's head of finance, risk and compliance, has released a statement telling of a "crack down on suspicious claiming and poor billing practices".
The claims from medical providers could include accidentally or deliberately billing for services not provided to obtain reimbursement, he said.
A new 0800 number has been launched to dob in dishonest claimants and a new fraud team was established in the last 12 months to try to stamp out fraudulent claims, possibly costing policy holders millions of dollars.
