A convicted fraudster who supervised the construction of the CTV building that collapsed in Christchurch will not face charges in Australia over allegations of identify theft.
Police in Australia and New Zealand have been investigating Gerald Shirtcliff over allegations he stole the identity of a British engineer and used it to work on dozens of high profile projects in Australia.
The University of New South Wales revoked Mr Shirtcliff's 1974 masters degree in highway engineering and the matter was referred to the police.
A spokesperson for the Australian Federal Police said on Monday no charges have been laid as no Commonwealth offences were identified.
A spokesperson for Christchurch police said the New Zealand investigation was continuing and the Australian decision has no immediate impact on that.
