"We're crying out for sections to be released for subdivision, and when we get that, we're going to go into boom mode here because the market's just going crazy."
Realty Services chief executive Ross Stanway said the latest figures reflected a continuing upward trend in the market.
Rotorua was seeing a lower percentage of new builds than Tauranga, but he noted that sale volumes had lifted significantly.
He confirmed there was a shortage of buildable land, but said pockets were becoming available.
"They are much needed. There is significantly increased awareness of Rotorua as a value-for-money proposition."
The growth in Tauranga reflected major new subdivisions in Papamoa, the Lakes and Omokoroa, he said.
"And particularly in Mount Maunganui, there has been a number of good strategically located older properties that have been bowled, with modern new homes going up."
