Housing Minister Megan Woods said it was great news for people and whānau in need of housing in the region.
"What's even better is that the homes will be built within the next three to four years," Woods said.
"Now that Kāinga Ora has bought these parcels of land for public and affordable housing, it's looking at the specific types of houses and apartments that will be built to help meet strong demand for homes for those most in need".
Development planning and high-level design work was underway for each site, and engagement with mana whenua and other stakeholders, neighbours and local communities would take place through the stages of development for each site.
The homes would be built to six Homestar energy efficient, warmth and sustainability standards, be landscaped and have good connections to the wider community, Woods said.
