Tightening of immigration rules by the government has New Zealand's already short-staffed trucking industry worried.
With an estimated shortage of more than 500 truck drivers in Auckland alone, companies have been bringing in workers from overseas to fill the skills gap.
Under the new rules announced by Immigration Minister Michael Woodhouse, migrants would need to earn more than $49,000 to qualify for a skilled worker visa.
Those earning more than $73,299 annually would automatically be classified as highly skilled.
Migrants earning less than $49,000 would only be eligible for a three-year visa, after which a minimum stand-down period would apply before they could renew it.
