Burley said a review of overseas job applications revealed an interesting trend.
"An inverse trend became apparent, IT median salaries would rise when overseas applications are falling and IT salaries would fall again when overseas applications are on the rise.
"This explains why Auckland has experienced the biggest drop in IT median salaries (down 2.5%) as it is also the area with the highest rate of migrant arrivals."
A short supply of IT talent in New Zealand has led to a job force with a very high ratio of overseas talent.
Orion Health chief executive Ian McCrae said while there are IT jobs available in the country, half of his workforce was from overseas.
Salaries for Wellington IT workers remained flat overall, despite being the region with the best IT packages - with a mediun salary of $87,000 and a $90 per hour for contractors.
Hamilton salaries rose 2.5 per cent, but IT contrators were hit the hardest, seeing the hourly rate drop by 17 per cent or $12 per hour to $60. The decrease was reflected in contract vacancies in the region.
