Mr Anderson said the increase in prices wasn't a surprise, and was driven by the market demand as well as an increase in property values which was leading investors to "protect their yield" and increase rents.
"It's obviously pretty good for the owner but not so good for the tenant."
Professionals McDowell Real Estate business development manager Stephanie Trainer said they had a huge shortage of three-bedroom plus properties.
She said those in the $200 - $350 price range was where they were seeing the biggest turnouts of potential renters.
Ms Trainer said because of values going up, and the demand, many landlords were requesting rent appraisals and reconsidering what they were charging.
"There is definitely still a huge shortage and we are still getting the CV and the whole life history of people applying, and people begging and pleading and you can only pick one."
She said landlords could now be pickier and it was becoming harder for those who had black marks against their name.
"An owner is much rather going to have someone who has paid their rent on time every time."
LJ Hooker Rotorua principal Malcolm Forsyth said it continued to be tough finding a rental in Rotorua.
Mr Forsyth said they were getting lots of inquiries and viewings on the properties they had available.
Not only was it difficult to find properties, but it was difficult for some people to pay the rents, he said.
"With rent prices going up that is on top of everything else that is going up and that is what is becoming more difficult.
"We have more people looking at what the options are, whether it's bunking in with others or staying at home a bit longer."
LJ Hooker had 10 properties available at the moment, but only three were under $300, he said.
Mr Forsyth said they carried out extensive checks and people who had made mistakes in the past were finding it much tougher to get properties.
"You have to keep the slate clean."
