Bill English's reshuffle marks another rise in the ranks for National's quiet star Amy Adams.
It is also a demotion for Nick Smith, who has now been distanced from any responsibility for the Government's house-building programme.
English today denied any suggestion of a demotion for Smith, saying reporters "should not read into it".
But his appointment of Adams appears to recognise that National is bracing for an election-year fight on housing and that Smith wasn't fit to lead it.
Adams was already responsible for social housing, emergency housing, and Housing New Zealand. She has now been given control over the National-led Government's plans to build tens of thousands of homes in the next decade.
