The civil engineer behind Christchurch's CTV building is no longer under investigation.
The Institution of Professional Engineers New Zealand had dropped its investigation into Alan Reay on legal advice, chief executive Andrew Cleland said.
Dr Reay's company designed the CTV building which collapsed during the February 22, 2011 Christchurch earthquake, killing 115 people.
Dr Cleland said Dr Reay resigned from IPENZ on February 28, but remains a chartered professional engineer.
IPENZ has authority to take action only over engineers who are IPENZ members.
‘‘After taking legal advice, IPENZ concluded the investigations could no longer proceed," Dr Cleland said.
He said the families of those killed in the building collapse had been informed.
Police announced in February that engineering firm Beca had been engaged to review information on the collapse of the CTV Building to see whether any criminal investigations should be undertaken.
Police said today the review was ongoing and they hoped to make a decision whether to proceed with criminal investigations later in the year.
