Reverend Perema Leasi on Housing NZ land that has stood empty since 2008.

"I don't mind who builds them, just build them."

That's the message from the Rev Perema Leasi, after news that New Zealand has nearly 4000 fewer state homes than it did two years ago.

He sighs every time he walks back on to empty land where previously Housing New Zealand homes stood in his Porirua community.

VIRGINIA FALLON/STUFF Porirua state houses were advertised for sale in September 2016 before they were taken off the market.

"It's been five years that I have been asking for homes to be built. I just repeat myself now."

Housing NZ's latest quarterly report reveals the agency's portfolio of 63,276 houses had shrunk by 3922 since 2015, including by 1132 properties in the past year.

PHIL WALTER/STUFF Housing Minister Amy Adams speaks with builders and works constructing houses designed to accommodate families in need on August 3, 2017.

Social Housing Minister Amy Adams said the majority of the homes had been transferred to community housing providers, but Labour housing spokesman Phil Twyford said that was splitting hairs.

"They've just shifted ownership instead of building more, that's why they're spending $140,000 a day on emergency accommodation."

While there was room for charities to provide social housing, it was up to the Government to increase its stock to meet demands, Twyford said.

BRADEN FASTIER/STUFF Phil Twyford said Housing NZ's homes shouldn't be decreasing in a housing crisis.

"We have a housing crisis yet we have a big reduction in state homes that hasn't been offset by community providers."

Last week the Anglican Church revealed that, as of April 30, of the 3500 hectares of Housing NZ land under management, 64ha was vacant – equivalent to about 64 rugby fields.

As the number of Housing NZ properties decreases, social housing waiting lists continue to grow, with 1476 more applications in 2017 than the previous year.

A Housing NZ spokesman said, despite having fewer homes, the agency had replaced outdated properties with new houses.

"During 2016/17 Housing NZ delivered a total of 1524 homes, including 1421 social, emergency and transitional homes, and 103 market and affordable homes."

The number of empty state houses had decreased, with 1592 vacant nationally in June, compared with 2486 a year earlier.

Adams was unavailable for an interview but, in a statement released by her office, said the homes had simply changed ownership and legal contracts meant they had to stay as social housing.

The almost-4000 figure included approximately 2800 homes transferred to the Tamaki Regeneration Company in Auckland, and 1138 social houses to Accessible Properties [owned by IHC] in Tauranga.

Adams stressed both were still social houses.

"We spent $2.3 billion on housing support this year, supporting more than 310,000 households. We've also committed $354 million for emergency housingthe first time permanent funding has been committed, which will provided 8600 emergency places each year."

National had committed to increasing the total number of "social" houses by 6400 within three years, she said.

Porirua City's state homes were some of the oldest in the country and many needed extensive work to bring them up to modern standard. she said.
