New Zealand has 72 large fixed cranes up - 29 in Auckland, 23 in Christchurch, nine in Wellington, five in Queenstown, three in Tauranga, two in Hamilton and one in Dunedin.
Chris Haines, Rider Levett Bucknall Auckland director, said his company's crane index showed how active the construction sector was because 43 new cranes went up in the past six months, mainly in Auckland and Christchurch.
