A truss and frame manufacturer will be referred to the Commerce Commission after an investigation into the use of non-load-bearing timber.
The Department of Building and Housing looked into the issue after it was revealed that sub-standard timber might have been used to build some houses in Auckland.
Building and Construction Minister Maurice Williamson says an initial report has found there is no public safety risk from the use of non-load-bearing timber.
Mr Williamson says a possible breach of the Fair Trading Act by one manufacturer will be referred to the Commerce Commission for further investigation.
He says a second manufacturer was investigated, but there appeared to be no further grounds to take action.
