An appeal was filed but the restaurant owner says there were next to no updates - his manager had to leave New Zealand and he was stuck in limbo.
That appeal was also declined in July.
"Immigration New Zealand consider three years sufficient experience to apparently do his job which . . . to me sounds like someone who's never done the job," he said.
"I have half a million dollars riding on this."
Sam Bratton, who has been in and out of the hospitality industry for 15 years, said three years' experience is not enough for restaurants aiming to have fine dining.
But officials said while an employer can specify a work experience requirement above the minimum standard, immigration must consider whether the employer has advertised the work in such a way that no New Zealanders are likely to apply.
An hour after the appeal decision came through, Bratton said his head chef, Keshan, handed in his resignation because he needed to move out of Auckland to get the necessary points for his residency application.
Migrant workers can get extra points that count towards residency if they live and work outside major centres.
For Bratton, it all came to a head when his sous chef was stopped from coming back into the country last month.
"He was on his way back from Italy, stopped in at Bali and they stopped him from getting on the plane," he said.
"This was all kind of like the 11th hour so he was supposed to arrive on Monday and Keshan had his last day on Wednesday."
Trying to find out anything from Immigration New Zealand was near impossible, he said.
Bratton only found out later on that his sous chef had not disclosed previous problems to authorities.
The owner said his dealings with Immigration had left a bitter taste.
"It's so frustrating because some of it is just such a simple answer and yet there's an utter refusal to have any kind of discretional policy. It's all black and white, to the book, and just like this is how it is," he said.
Immigration New Zealand told RNZ while it accepted Bratton was frustrated with the process, without privacy waivers from the individual workers involved it was unable to give specific details about their cases and visa applications.
Hospitality New Zealand said it was no secret that restaurant owners rely heavily on workers from overseas.
Its policy and advocacy manager, Nadine Mehlhopt, said there just were not enough New Zealanders who want to get into hospitality and being told to hire locals can be a problem.
"Having to employ people who aren't necessarily wanting to work in hospitality specifically or who aren't necessarily the best suited for it - you end up having to spend quite a bit of time in training which may not pan out," she said.
Mehlhopt said that can slow down productivity, put customers off and ultimately affect revenue.
Bratton has been working seven days a week, opening his restaurant early in the morning and closing late in the evening, to cover for the lack of staff.
And he had a message for Immigration New Zealand.
"Have some emotion in what you're doing," he said.
