Real Estate Institute of New Zealand spokeswoman for Rotorua and First National principal Ann Crossley said new borrowing regulations had impacted investors.
She said they her company had listed three properties recently which would have been perfect for investors but had instead sold to first home buyers.
Ross Stanway, chief executive of Realty Services, which operates Eves and Bayleys Real Estate, said without a doubt more people were looking at Rotorua as a place to invest or live - and the figures reflected that.
He said the increase in value supported what they were seeing both at Bayleys and Eves with increasing prices and volumes.

He said there was still strong local demand with people moving within Rotorua either upsizing or downsizing but there was also interest from Aucklanders and people from other parts of the Bay.
Mr Stanway said his businesses hadn't seen any winter slowdown.
