In Tauranga, there were 226 houses sold last month. Last year, there were 250.
Despite the reduction in sales volumes, the Western Bay experienced an increase in median house prices and was the only area in the wider Bay to do so.
Western Bay median house prices went from $535,000 to $556,000 last month but Tauranga's prices went from $595,000 to $585,000.
Regional director Philip Searle said more listings were slowly coming to the Bay of Plenty market and auction clearance rates had improved.
"Prices are still holding firm with premiums being achieved for quality property. However, there are more conditional deals now that are subject to sale of an existing property of finance, and lending in the region is still restrictive.
"Looking forward, we anticipate more of the same with some investors selling as they are concerned by the talk coming from the new Government."
