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.
