Immigration New Zealand figures show eight applications, representing 21 people, have been approved in the Northland region.
Mr Thomas and his wife Dissmol Devassy work as nurses in Whangarei and applied for their permanent residency in December.
He first came to Whangarei in February 2012 and spent two years studying nursing at NorthTec before applying for a job as a nurse at Whangarei Hospital.
The couple got married in September last year and Mrs Thomas works as a nurse at a rest home in Whangarei.
They have no plans of moving elsewhere even after getting their permanent residency.
"There are many reasons people should come and live in Northland ... climate, it's a quiet place, less expensive but probably the main attraction is NorthTec where the support for international students is excellent," Mr Thomas said.
Women's International Newcomers Group Social (Wings) coordinator Liane Blair hoped the new policy would help attract more migrants to Northland.
"I know that some people have had to go to Auckland. They'd prefer to be up here but they go where the work is."
