New Zealand has seen a spike in numbers of Indian nationals wishing to move here in the various categories in recent years, including as skilled migrants and international students.
Ms Hogg said those seeking to work here needed to ensure that they were getting their immigration information from a credible source.
"While people are free to find out for themselves about the requirement for work in New Zealand, work opportunities and to arrange jobs, anyone who needs immigration advice should only use a licensed immigration adviser."
James Ellis, director of Edvantage International Consulting, an educational agency in Auckland, said one of his clients who studied at a private management school in Singapore paid $4000 to go through a job interview for a fictitious Kelly Services offer to work in food and beverage for Takatu Lodge and Vineyard in "Matakata" Auckland.
The student was promised a salary of $28,600 and was told the contract was renewable after two years.
In a letter to Immigration, Mr Ellis said he believed hundreds of students could have been "lured" to study in Singapore because of the promise of work in New Zealand.
"I am concerned about the scam or fraud ... promising unsuspecting and vulnerable students work permits in New Zealand," he said.
Kelly Services general manager Victoria Robertson said the offer was not genuine and that it had not been supplied or sold by any member or authorised representative of the company.
She said there were a number of elements in the offer letter that were "patently false", including the brand and layout, address and the person named in the contract had never been an employee of the company.
Ms Robertson said the company did not charge to source for employment and letters of offer were made only when there was a genuine offer for work.
"We have followed up this matter with the relevant authorities and have made our global team aware of the false use of our brand in this regard."
