Recently completed office buildings have created new pockets of vacancies outside Auckland's CBD, contributing to a 1.6 percentage point increase in the metropolitan office vacancy rate.
The latest Colliers International metropolitan office survey found overall vacancy increased to 6.7 per cent in September 2018, compared with 5.1 per cent a year ago.
The prime vacancy rate has remained steady, at 5.4 per cent, since the last survey in March. The secondary vacancy rate has risen to 7.1 per cent, up from 6.2 per cent.
Colliers' survey excludes properties in the CBD, focusing primarily on activity in the city fringe and suburbs.
Colliers director of research and communications, Chris Dibble, says 38,660sq m of new metropolitan office space has been completed in Auckland since the start of the year.
