Overall 10,160 homes have been contracted and committed under the scheme.
So far 53 homes have actually been sold, including homes sold off the plans.
There had been just 289 homes prequalified, with 47,853 registered expressions of interests.
Prime Minister Jacinda Ardern yesterday defended the Government's flagship KiwiBuild programme despite it being drastically behind schedule.
"Ultimately, the true goal has been to address the housing issues we have in New Zealand and that includes state housing, that includes community housing, that includes addressing homelessness, and it includes affordable housing," Ardern said, speaking to reporters from Switzerland where she was attending the World Economic Forum.
"We set some goals around KiwiBuild and even if we're falling shy of those, we are still building affordable houses, just not as fast as we want and as many as what we want as quickly as we want," she said.
National's housing spokeswoman Judith Collins said Twyford was letting down thousands of Kiwis.
"If he can't organise the delivery of 1000 houses a year, why on earth would we believe the minister when he says he's planning on building 10,000 houses a year," Collins said.
