But John Key was ready and waiting. He responded by holding up a photograph which he said showed there were already houses on the other side of the substation's boundary.
"They are just there, you see? If you can build them there, I guess you can build them on the other side, I suppose."
Key had to be taken at his word. The photograph was too small for anyone to tell.
Little struck back, asking Key if he had been advised that there had been an explosion at the substation in question which had cut power to much of west Auckland.
Little then sought a categorical denial that the Mangere Lawn Cemetery was on any of the lists identified by the Government as residential land.
But - to no-one's great surprise - Key did not have the relevant list in his possession.
But Key had a point of his own to make. Or rather "a bit of logic".
If Labour was saying there was no land available for housing, how on earth would it have been able to fulfill its election promise to construct 100,000 homes over ten years?
