"I can see what's behind the decision and it's good for the regions, but I'm not sure when we are going to see it," she said.
"It takes a while for the points system to become a reality."
However, she was confident Rotorua was well placed to take advantage of any future wave of economic migration - particularly in the spa, health, wellness, and forestry industries.
She gave the example of the city's recently founded Chinese Business Association as proof the city was in a position to attract international investment to provide viable new jobs.
"I'm working very hard with the community to find investors who want to stay here for the long haul," said Mrs Chadwick.
Skilled migrants taking advantage of the new system would have to commit to working in the regions for at least a year.
Rotorua Chamber of Commerce chief executive Darrin Walsh said he welcomed any policy that "attracts people here and helps us grow".
But he warned against complacency when it came to attracting new talent.
"If the jobs are in other regions [apart from Rotorua], they will go there. The people coming into the regions are going to come [only] if the positions are there."
Lewis Whitworth, owner of Rotorua airconditioning and refrigeration company Aventurine, emigrated to New Zealand from England in 2010.
Although he eventually gained residency through his Kiwi partner, Mr Whitworth said he had made it halfway through an application as a skilled migrant.
Another 20 points for moving to the regions would have helped with his application.
"It would have made a big difference."
Keri-Anne Tane, general manager people and performance at Scion, which employs a number of people from overseas, said: "We consider the change may support our international appointments to speed up their applications, as well as recognising the contribution our international staff make to the region".
