Pukeroa Oruawhata Holdings chairman Malcolm Short said the company had been planning a number of new developments at the Rotorua Central site for some time.
He said the Warehouse Stationery store would be rebuilt and open for business by December this year, while a new building for the ANZ bank and surrounding tenants was now under construction and would open by April next year.
Mr Short said The Warehouse building was also undergoing a complete refurbishment and the northern end of the mall looking out over Amohau St would be fully enclosed.
"We continue to receive very substantial interest for space and we are actively pursuing development opportunities where they prove to be financially viable," Mr Short said.
He said the remodelled food court, that was completed in time for last year's Rugby World Cup, had proven to be very successful and well supported by the residents of Rotorua, as well as visitors to the region.
"All the food court retailers are delighted with business and as a result, we have made a decision to develop the mall further and to completely enclose the balance of the mall out to Amohau St.
"This will mean that our customers will have a totally covered environment and will be weather protected all year round ... and offers retailers the opportunity to trade in modern and up to date premises."
The company has employed the Retail Consulting Group (RCG Ltd) as development managers and architects which would be lodging building consents in September, with construction work to begin early next year.
Mr Short said the total value of the work would exceed $13 million, saying the new developments demonstrated the success of the centre's retail environment and Pukeroa was delighted to be able to continually improve its facilities for the betterment of retailers and their customers.
He expected a further announcement to be made in a few months regarding another development on the site and acknowledged the support of the Rotorua District Council in enabling their projects to be brought to fruition.
