Families living near air force bases whose water supplies have been contaminated with a toxic foam are still waiting to find out if they face health problems as a result.
The Defence Force has admitted chemicals used in firefighting foam before 2003 have leached into nearby soil and water at the Ohakea and Woodbourne bases. People living in five homes at Ohakea and two in Woodbourne, where the drinking water was found to be contaminated, have been offered free blood tests.
Studies have linked the toxic foam to testicular and kidney cancer, tissue damage in the liver and a lowered immune system.
Ministry for the Environment chief executive Vicky Robertson joins Guyon Espiner.
"We could have done better about communication," she says. "We wanted to focus on those families we knew were above the [contaminated levels]."
