The students said they paid the money, often in cash, to Team Migration New Zealand, and entered into a four-month contract, during which the company would find them employment.
But with many of the contracts having expired, the students have not been given refunds and allege they are being stalled by company chief executive Reshmi Pratap.
However, Ms Pratap said the students had either breached contracts or had not contacted her about a refund.
Jessica Wang (23) said she was owed $10,000 by the company, which failed to find her work, or even an interview, within the four-month period.
She came to New Zealand from Beijing in 2002 to study and graduated with a bachelor of commerce degree in economics last August.
She approached Team Migration after hearing about its work through a friend and on the Internet.
She understood she would pay the company an initial fee and it would find her work within four months or the money would be returned.
Her contract states that if by the end of the four months there had been no success, the company had the discretion to refund the money, or offer a further period where it would try to find employment at no further charge.
When Miss Wang's contract expired on February 28, she asked for a refund.
Since then, Miss Wang has twice visited the company's Christchurch premises seeking a refund, but without success. On the last visit, she said the office was bare except for one desk.
Miss Wang received a call from police on Friday saying she and her boyfriend should stay away from the company's premises or face trespass notices.
She has also used legal help, costing about $2000, in an unsuccessful attempt to get Ms Pratap to repay the money.
A group of students who had been affected were banding together in Christchurch to approach a member of Parliament with their concerns, she said.
Grant Zhang (23) said he had paid $15,000 to the company and had not been contacted about any jobs.
Kelly Chen (26), a University of Otago accounting graduate, said she was owed $10,000 from the company.
She was found casual work which was not suitable as the employee did not have time to train her.
Team Migration told her she had breached her contract and she was unable to get a refund.
Team Migration, which specialises in finding jobs for Asian graduates, has been operating since 2006 under chief executive and director Ms Pratap.
Ms Pratap said, when contacted yesterday, she did not believe there were 14 students who were owed money, but if there were she had the money and would repay them.
She said she had been away "seven or eight times" in the past 12 months and that communication between her and job brokers employed by the company had lapsed.
Ms Pratap said she was trying to sort out the "mess" and if the students concerned wrote to her they would get a refund within 21 days.
However, she said she could not afford to give refunds to "every student", even if their contract had expired.
She said some of the students had breached their contract conditions and were therefore not entitled to a refund.
Immigration lawyer Mark Williams, of Christchurch law firm Lane Neave, confirmed he was acting for at least three people who had complained about Team Migration.
