Two big projects in Christchurch are immediately affected by Mainzeal’s collapse.
Christchurch Earthquake Recovery Authority chief executive Roger Sutton says Mainzeal has nearly completed the work of demolishing QE11 sports centre and the Clarendon building in Oxford Tce.
“We’ve had a couple of phone calls with them today and we’ll be having more discussions with the receivers.”
Mr Sutton downplayed the ramifications on the central city rebuild, noting the dynamism of the construction industry as different players came and went.
He is less certain of the implications for Mainzeal's involvement as project manager for Vero to repair houses. One-third of the 90,000 house repairs have been completed.
Mr Sutton speculates that the Mainzeal collapse might even have a positive, indirect, spin-off for Christchurch.
Construction industry staff might be prompted to seek work in the city sooner.
Meanwhile, the position of sub-contractors remains unclear. Some have complained about being unable to recover tools from stalled construction sites.
