Whanganui vendors made a median profit of $75,000 in property sales during the first three months of 2018.
New figures from property information company CoreLogic's "Pain and Gain" report show Whanganui property owners pocketed $21 million in gross profit from sales in the first quarter of the year.
CoreLogic senior research analyst Kelvin Davidson said the property market was generally in good shape, with losses from sales remaining at historically low levels.
"We'd anticipate property values continuing to rise modestly over the rest of the year, given that migration is holding up, investors are staying in the market and interest rate rises remain a fair way away," Davidson said.
"There's a bit of evidence of uncertainty for investors and in the apartment sector but it's minimal. This is consistent with the continued gains in overall property prices in most parts of the country."
