Immigration authorities say they've now identified nine witch doctors following allegations of unethical or extortionate behaviour by black magic practitioners.
Five of the so-called witch doctors have now left New Zealand, Immigration New Zealand (INZ) said today.
"The four who remain in New Zealand and hold visitor visas appear to be in breach of the conditions of their visas and appear to be liable for deportation," INZ assistant general manager Peter Devoy said.
The individuals have been asked to respond to INZ's concerns before a decision is taken on what action to take.
"INZ would strongly encourage people not to be taken in by anyone offering these types of services," Mr Devoy added.
The suspected witch doctors were operating mostly in the Indian community.
Yesterday, community leader Pratima Nand said witch doctors had established themselves in several New Zealand cities.
Ms Nand she'd received about ten complaints from people who had believed witch doctors could help with finance, business, love, health and even immigration issues.
Some of these people handed over personal details and photos to the witch doctors.
Mr Devoy said authorities were grateful for the public's help in highlighting the witch doctor activities.
"We would encourage anyone else with information on individuals involved in this type of activity to contact our Contact Centre on 0508 55 88 55 or make an anonymous complaint via CrimeStoppers on 0800 555 111."
