A rapid review into the health system response to lead contamination in Karitane and Waikouaiti’s drinking water supply
is underway.
Sample results from the Waikouaiti drinking-water supply have shown intermittent spikes in lead levels above the maximum
acceptable value.
The source of the contamination has not been identified and it is not clear when these spikes in lead concentration
started. This is currently under investigation by Dunedin City Council.
“I have asked the Director-General of Health, Dr Ashley Bloomfield to conduct a rapid review by independent experts to
ensure public confidence in the health response. This review will also inform the three waters reforms that are
currently underway,” Associate Minister of Health Dr Ayesha Verrall said.
“The communities were advised to stop drinking water from the supply on 2 February 2021. They are currently being
provided with tankered drinking water until authorities get to the bottom of the problem.
"A short high spike in lead levels on its own is unlikely to cause toxicity, but the free blood tests being offered to
residents will help determine if there has been longer term exposure.
“New Zealanders have every right to expect that their drinking water is safe. What’s happened in Otago is unacceptable.
“While it is vital that we understand how levels of lead contaminated the water, we also want to review our overall
health response to the situation. The independent review will look into how the health system, including local and
central government health agencies, responded to the situation and how the risk to public health was subsequently
addressed.
“Ultimately, we want to reduce the risk of this happening again and inform the ongoing response. I expect the
Director-General to report back to the Government on the preliminary findings and suggested actions by March.
“The Government has been clear for some time that there are long standing infrastructure issues with our water systems
throughout the country and we are addressing that through the three waters reforms.
“The Ministry of Health will announce the Terms of Reference and review panel in the coming days,” Dr Ayesha Verrall
said.
