Pukeroa Oruawhata Group's general manager Peter Faulkner has announced he will leave his role.
"Peter has been involved with the group for just on 25 years, initially as our banker, then as our general manager for the last 11 years," the group's chairman Malcolm Short said in a statement.
The resignation will be effective August 31.
"Since his appointment in 2010 as our general manager, the value of our balance sheet has grown from $120 million to what is expected to be $335 million this year.
"Our strategic vision has always been not simply about building buildings, it's been about building sustainable income streams from which to deliver ongoing benefits to our owners and our City," Short said.
