Combined, all re-sold properties over the quarter generated total gains of $49m.
Total resale gains in Hastings were even greater, hitting a total of $65m, with a median profit gain of $168,300 per re-sold property.
CoreLogic analysed the homes that were sold during the three months to June 30, comparing the most recent sale price to the previous sale price to determine whether the property sold at a gross profit or gross loss.
Hawke's Bay realtor Tremains pointed out that while the "dollar" gains in Napier were higher than Hastings, the actual percentage gains were similar for both cities.
"For me, that just comes back to average house price. The higher the house, the percentage profit is probably similar but if you are talking dollars then obviously it's higher," managing director Simon Tremain said.
"It's amazing actually, how close the volume of sales is for each city. Everything is very similar in both cities but the average house price in Napier is higher than Hastings.
"Given the way our market has moved, I would have thought most sellers will be selling at a profit at the moment."
