Travellers who bring so-called Fijian "miracle water" into New Zealand are being warned they risk a $400 fine.
Media in Fiji have run stories on the claimed healing properties of water from in the village of Natadradave, in the province of Dawasamu.
Mountain water taken from behind a dam is said to have healed illnesses including conjunctivitis, according to a report last year in the Fiji Sun.
"We have an old dam and during hot weather it dries up and we have to go to the river to fetch water," Natadradave village headman Tomasi Naisoso told the paper.
"People went up to the dam to bath and wash their eye and within days the virus would disappear."
