Health New Zealand has reported a spike in reported cases of vomiting and diarrhoea at the top of South Island, after recent flooding.
The health agency said floodwater and silt could be contaminated with faces, and agricultural or industrial waste, and often carried bugs that could cause gastrointestinal illnesses.
It said the overall number of cases reported to the public health service in Nelson-Marlborough was small, but investigations showed many had been exposed to the flooding.
However, it was unable to directly link the outbreak to contaminated drinking water or food caused by the flooding, or contact with flood-contaminated land and water.
A spokesperson was unable to confirm the number of cases.
The agency said, while the Tasman District Council had tested its water supply and had no concerns about water quality, it had advised bore-water owners and those who had been issued with a notice to boil their water as a precaution.
"People should treat all surface water as contaminated, and keep children and pets away from contaminated areas, until they have been cleaned up."
Health NZ said people cleaning flood-affected areas should cover cuts and wounds, wear a mask, and wash hands thoroughly before eating and drinking.
It encouraged anyone with symptoms of gastrointestinal illness - including diarrhoea or vomiting - following the floods to call Healthline or contact their general practitioner.

Gore water now safe to drink
Photo: RNZ / Cole Eastham-Farrelly Gore District Council has lifted the do not drink notice on the township's water supply following a third day of testing beneath the national limit. The municipal water supply has been off limits since Friday after a monthly sample breached the drinking water standards on Friday. Spokesperson Jason Domigan says levels in one well are still higher than normal, and the council would work with Environment Southland and water regulator Taumata Arowai to find out where the spike is coming from. Elevated nitrate levels pose a particular risk to pregnant women and formula-fed babies, but even relatively low levels have been linked to bowel cancer in some international research. The council says if people are unsure if their tap water is ready to drink, if they've already used the taps for showers, baths or toilets it was likely good to go. "Otherwise, just run the tap for a few minutes before drinking or brushing your teeth." A water tanker would remain at Eccles Street Playground for the next few days for anyone who wanted to access water there.

Booze Warnings On Hold
, for The Detail Outdated alcohol guidelines put New Zealand out of step with modern research, but our health authorities are in no hurry to update them. In Canada, proposed guidelines for low-risk drinking set the weekly limit at two drinks. Here in New Zealand, the recommendation is to cap alcohol at 10 drinks weekly for women, and 15 for men, with two alcohol-free days per week. Despite these guidelines being nearly 15 years old, and documents from Health NZ showing that they consider a review of the guidelines to be 'necessary', for now, the guidelines are staying as they are. "The complication is that the Ministry of Health has come in over the top of [Health NZ] and has said 'actually these are our guidelines ... we want to control this and we're putting a pause on that work'," says RNZ's Guyon Espiner. "It certainly does show that they're listening to the alcohol industry, who are pretty exercised about this - because as you can imagine, this could have a significant effect on sales if people did take this advice and did drink significantly less." In a series of articles over the past few months, Espiner has reported on issues of alcohol harm and how the alcohol lobby has impacted policy in New Zealand. Through documents he received through the Official Information Act (OIA), he found that Health NZ commissioned a review of the low-risk guidelines. But in October 2024, a lobbyist emailed Ross Bell, who is a manager in the Ministry of Health's Public Health Agency, asking why Health NZ's website said the guidelines were under review. In December, following a second email which again asked about the review and also complained about mention of the Canadian guidelines on Health NZ-run website ' Bell emailed Health NZ saying "All work on this project will now pause. You will update relevant Health NZ websites to remove references to the review and also to other jurisdictions' guidelines (including the Canadian one)." But in a statement to The Detail, the Ministry of Health says it "understands Health New Zealand has continued some work related to the review. The Ministry is working with Health New Zealand on potential next steps, including how Health New Zealand's progress on the review to date can be used to inform any future work in this area" and that "the Ministry is currently considering where the next phase (Phase 2) will fit as it prioritises its work programme for 2025/26." The Ministry's statement, which is attributed to Dr Andrew Old, Deputy Director-General, Public Health Agency, goes on to say that "as part of good policy process, the Ministry engages with a broad range of interested parties-including community organisations, public health experts, and the industry-to ensure any regulatory approaches are well-informed and transparent. Reference to the drinking guidelines review was removed from the website to avoid confusion about roles and responsibilities as the guidelines are now led by the Ministry of Health - rather than Health New Zealand which has responsibility for the site. This was an internal Ministry decision." In today's episode of The Detail, Espiner details other examples of contact between the alcohol lobby and health policy makers. "The material I've got shows that yes they've had a lot of meetings, a lot of email contact, in fact one looked like a regular meeting between alcohol lobbyists and Ministry of Health staff. They've also shared with the alcohol industry their plans on how they will combat Fetal Alcohol Spectrum Disorder ... they shared that entire draft document with them and also shared with them plans about how they might spend the alcohol levy." Espiner says that while this contact is going on, tobacco lobbyists are completely 'locked out of the policy process". "We're signatory to the Framework Convention on Tobacco Control, [which is] a World Health initiative, and there's a clause in there that New Zealand is signed up to that says you won't allow the vested interests of the tobacco industry to shape policy. "What's interesting is that the alcohol industry has escaped most of that scrutiny." For Massey University associate professor Andy Towers, who has worked on the Health NZ review, it is a clear mistake for New Zealand to allow lobbyists a role. "It's very, very clear that you don't invite the wolf into the henhouse," he says. "Unfortunately the alcohol industry makes money based on alcohol use and resulting alcohol harms and in a space where we are trying to reduce the harmful use of alcohol and reduce those harms for society and for communities, there is not space for the alcohol industry there. They do not get to sit at the table, just as you wouldn't invite an arms manufacturer to the table to talk about cessation of violence." In this episode of The Detail, Towers explains how knowledge around the harm of alcohol has evolved in the past 20 years, and where New Zealand sits on alcohol use compared to other countries.

Two popular regional flights on the chopping block
Two popular regional flights in the South Island are on the chopping block due to what is has been described as 'out of control' costs. Sounds Air will soon can its flights from Blenheim to Christchurch and Christchurch to Wanaka. It comes after the airline cancelled its services from Wellington to Taupo and Wellington to Westport last December, and sold an aircraft. It has been seen as not just a blow to hopes of boosting tourism but also for healthcare and those needing treatment at Christchurch Hospital. Tess Brunton reports.
