The bulk of the amount was for compensation, outstanding salaries and holiday entitlements.
Ms Colos said yesterday that she did not have the money now and could make the payments if she was given an August deadline.
"Out of my eagerness of wanting to settle everything, my unrealistic promise was to pay by December," she said.
"I'm not turning my back ... It's really hard for me to raise $40,000, it's really impossible, I don't know what to do."
Ms Colos claimed the migrants were complicit in the employment arrangements so that they could obtain residency in New Zealand. She said she could not afford a lawyer.
One complainant, Sharry Ocampo, who is five months pregnant and is owed $4781, said the refusal to pay had made her feel "insulted and humiliated all over again".
Ms Ocampo, who is unemployed, said she needed the money to give her some financial stability during her pregnancy.
Last August, the Herald revealed that five workers complained to the authority about Ms Colos and her E-Advance company, claiming they were asked to pay up to $15,000 to secure employment, were not paid wages and pressed to lend money.
Some said they were forced to live in the company's level-four office at Albert Plaza in the CBD - where they did not have access to bathroom or kitchen facilities - after they ran out of money for rent and food.
Ms Colos had agreed during mediation to pay one quarter of the agreed sum on November 27 last year, with the rest being split over deadline dates in December, January and February.
A further order was made last month for Ms Colos to pay the outstanding amounts, after payments were not received.
Lawyer Oliver Christeller said he was lodging a complaint in court under section 137 of the Employment Relations Act. Under it, a person in default could be jailed for up to three months and fined up to $40,000.
Dennis Maga, co-ordinator for migrant workers union Unemig, said it was important that all was done to ensure Ms Colos met her legal obligations, otherwise it could send the message that employers could "get away easily" with exploiting migrants.
Waiting game
• Migrant workers are taking their former employer to court after she failed to meet an Employment Relations Authority order to pay them owed money.
• Auckland woman Norajane Colos had been given until March 27 to pay $38,796.
• Determinations from the authority showed Ms Colos had managed to pay only $3000 for an airline ticket, citing financial problems with her companies.
• No further payments had been received as of yesterday, and the lawyer for the workers said a complaint would be lodged in court today.
• The bulk of the amount was for compensation, outstanding salaries and holiday entitlements.
