Hon DAVID PARKER (Minister for the Environment): Talofa lava. I have met with the Associate Minister of Health, the Hon Dr Ayesha Verrall, together with the Director-General of Health to discuss the matter, and I understand the Ministry of Health is reviewing the various studies and will thereafter recommend whether or not further study is undertaken in New Zealand. If, eventually, nitrate levels were to be further tightened in New Zealand for drinking water standards, that would be a health-led issue rather than for me as Minister for the Environment.
