Realestate.co.nz said its 2015 first-quarter listings for Katikati were 126, up from 101 over the corresponding time a year earlier, while Te Puke numbers rose from 70 to 83.
Eves and Bayleys Real Estate chief executive Ross Stanway said Katikati was tracking in the same direction as Tauranga and Mount Maunganui. Interest from outside the region was higher and evident in sales to Auckland and Waikato buyers, he said.
"It is tracking upwards from 12 months ago when it was 50 per cent from outside the region and local people" he said.
Claridges Real Estate Katikati principal Merv Gardiner said there had been a big increase in Auckland buyers, and people from Tauranga were moving. Houses in the $350,000 to $500,000 were shifting the fastest. "Katikati is growing and there is room for expansion ... a lot of other regional small towns aren't going very well."
In Te Puke, Century 21 branch manager Russell Doughty said: "It is very busy ... probably 25 per cent of the properties sold recently were to investors ... with Aucklanders buying rental properties."
Eighty per cent of sales had been in the $300,000-$400,000 range.
Harcourts Katikati franchise owner Kevin Devitt said sales in the town had been going "really well".
"Listings around New Zealand are getting harder to find, people are resisting putting their homes on the market at the moment, maybe it's the winter blues. Those that are being put on the market are selling quite readily and we're getting quite a few multi offers."
Mr Devitt said the big demand in Katikati was for homes in the $350,000 to $500,000 price point, and producing orchards were also getting harder to come by.
Western Bay of Plenty District Mayor Ross Paterson said the housing market activity was positive and the council had been investing into infrastructure so it could cope with potential growth.
"We have made a commitment so we won't put people off and say you can't subdivide because we can't handle your wastewater.
"That has been our investment now and that will stand there for the future as these people come into the community."
