In June 2016, it was 17 "at-risk" and seven "serious", with just two homes available.
In September that year, the figures were 23 and 10 and there was not a single state property to be had.
During that time, Housing NZ was selling off houses, its stock in Whanganui falling from 604 to 572.
Behind those disturbing numbers are human stories of hardship and misery, but they are much harder to statistically quantify.
It is merely anecdotal evidence that suggests some of those families will have moved in with relatives; some will have joined the long queue to find a home in the very tight private rental market; and some may well have joined the ranks of the homeless, perhaps sleeping in a car.
Alongside Housing NZ's failings, we had PARS (Prisoners' Aid and Rehabilitation Society) struggling to find accommodation for former inmates and the Salvation Army desperately trying to acquire emergency housing.
Despite a worrying consistency in failing to get anywhere near matching demand, Housing NZ deemed Whanganui an area of "low demand".
There has clearly been a re-think.
The decision to build nine new houses is a response to growing demand, it says.
It is a decision and a change of attitude to be welcomed and applauded.
