With both Rotorua Central Mall and Trade Central now both fully developed and essentially leased, the group had a solid platform to move forward from, the statement said.
"Peter has been closely involved in getting us to where we are today and his decision to step aside and the reasons for that decision are respected," Short said.
"Peter will continue to make himself available to both support the transition process and to see the Wai Ariki Hot Springs and Spa through to completion."
Faulkner said the decision to not renew his contract was "all about timing".
"I received a bit of a wake-up call on the health front a couple of years ago which helped put things into perspective for me.
"With the group's core assets now substantially fully developed and the Lakefront development about to start, now is the right time to introduce a fresh set of legs to take the group on the next stage of its development.
"The group has an exciting future ahead of it and I look forward to following its successes in the years to come."
Recruitment for the general manager's role was under way and an appointment was expected to be announced by July, Short said.
