Auckland has 33 cranes dotting its skyline, with the construction sector in full swing.
The Rider Levett Bucknall Crane Index revealed that Auckland is the country's crane capital followed by Christchurch with 31.
Auckland director Chris Haines said there were now 79 cranes up nationally and the busiest sectors were commercial followed by multi-level residential buildings.
In the past six months 43 new cranes were installed nationally: 17 in Auckland and 23 in Christchurch.
The crane count provides a good, simple indication of new building activity as well as general economic activity in each of these locations, the business said.
