An undercover sting in India, organised by students facing deportation, has revealed the immigration agency that helped them get to New Zealand is still offering the same services - and the same suspected document fraud.

A lawyer representing some of the students, Alastair McClymont, said it was business as usual when one student visited the office last Monday.

Mr McClymont said another immigration advisor in Punjab was granted a license by the New Zealand Immigration Advisors Authority, despite proven financial document fraud.

He said having the licence gave the agent more credibility.
