Queenstown's building boom has pushed crane numbers up 600 per cent in the last few months.
The RLB Crane Index, out this month, found the southern tourist mecca had the biggest increase in cranes numbers since earlier this year, followed by Auckland where crane numbers rose 156 per cent, Wellington 83 per cent and Christchurch 14 per cent.
Queenstown has almost double the numbers of cranes since the last survey. Seven cranes could now be seen in the region around Queenstown on six sites, RLB said.
"Both the commercial and civil sectors have each had cranes erected on new projects. Two commercial cranes have commenced on sites at Beach Street and Five Mile Stage
two and two cranes have commenced works at Kawarau Bridge within the civil sector," the survey found.
But people who fear crane numbers are a harbinger of doom shouldn't worry, according to an RLB executive.
