Ms Tau said no child in her whanau had been injured on a driveway but she knew such tragedies had occurred in Kaikohe. The programme began last November with the aim of reducing the risk of children being run over in the driveways of state homes by creating fenced-off play areas for children.
Another 25 Northland homes will have improvements made in the next few months.
Housing New Zealand Northland manager Neil Adams said the priority was to make safety improvements at properties where there were children aged 5 and under, as toddlers were at the greatest risk of being injured in a driveway accident. The improvements ranged from installing fencing, self-closing gates with child-resistant latches, speed restriction signs, speed humps and convex mirrors where appropriate.
"The work we carry out depends on the type of property - but the key priority is creating fenced play areas for childrenwho are separate from the driveway," Mr Adams said.
New Zealand has one of the highest recorded rates of child driveway death and injury in the world, with a child hospitalised every two weeks.
