A campground in New Zealand is set to reopen after a norovirus outbreak was linked to the camp’s water supply.

The Nelson Mail reports the outbreak of suspected norovirus at the Golden Bay Holiday Park may have been caused by sewage contaminating a creek running through the campground

During a routine bathing water survey of the area’s beaches a fortnight ago, Tasman District Council environmental protection officers found high levels of E.coli contamination at the mouth of the Tukurua Stream, which runs through the campground. The level was 700 most probable number (mpn).

Council environment planning officer Dennis Bush-King said a level of 240mpn would see the council start "intensive monitoring". At 500mpn, signs would go up warning people not to swim in the water.
