The first house is rising at Todd Property's new Long Bay residential estate on the northern outskirts of Auckland.
This is the biggest new residential development in New Zealand, a 160ha estate where more than 2000 places will be built for about 5000 people.
A Todd spokesman said G.J. Gardner was building in Ara Place, the show home street.
G.J. Gardner is the country's largest group house builder, its franchises put up more than 500 places annually.
"The first residents should be moving into their homes in time for Christmas," the spokesman said.
