Sub-contractors are understood to be owed millions of dollars after the collapse of North Island building company Stanley Group and related companies.
Three Stanley Group companies were placed in voluntary liquidation yesterday along with Tallwood Holdings and its subsidiaries based in Takapuna, Auckland, and Matamata in the Waikato.
The business, which has about 100 staff, had projects on the go for Housing New Zealand in Mangere, Hamilton and Whakātane.
A creditor told the Herald some sub-contractors hadn't been paid "for months" and the situation came to a head on Wednesday when Housing NZ intervened.
It is understood the government agency had to step in and pay sub contractors, but many are left out of pocket and still chasing payment.
