Housing New Zealand Corporation sold 174 properties nationally in the past year for a total of $42.2 million.
The Government agency got the biggest windfalls from high-priced Auckland sales, where 11 houses yielded $9 million.
Sean Bignell, the general manager of asset development, said the corporation had a policy of selling high-value properties, expected to fetch more than $700,000.
That money was then reinvested into housing for those most in need, he said.
Housing NZ sold 39 Spencer St, Remuera (valued at $770,000), for $1.3 million and 58 Wainui Ave, Pt Chevalier (valued at $740,000), for $850,000.
