Pick your way through the latest batch of just-released Cabinet papers dealing with the future of state housing and you will find the reason why the National minority Government is struggling to sell the virtues or otherwise of its radical reform of the bottom end of the housing market.
It comes down to simple bricks and mortar. Or the lack thereof. The officials who wrote the documents talk of ministers intending to give "external audiences" the constant message that the "conversation" about social housing needs to change from being focused on how many houses will remain under Housing New Zealand's control - and thus in state ownership - and how many will be sold to "community housing providers".
National is trying to shift attention to its objective of getting better housing outcomes for "poor and vulnerable" New Zealanders - and that it no longer matters who owns the house or who provides the accommodation-finding service.
There is an adage that if you're able to frame the argument on your terms, you are halfway to winning it.
Try as it might, National has been unable to reframe this particular debate. National is handicapped by the sheer complexity of its bold plan to establish a market for social housing where voluntary organisations register as community housing providers and compete with a pared-back Housing New Zealand.
