Dental services for children in parts of Hawke's Bay will be affected after thieves stole a mobile clinic.
The clinic, which looks like a large caravan, delivers dental services to children in and around Wairoa.
It is worth between $150,000 and $250,000 and contains an X-ray machine, needles and filling material which contains mercury.
The vehicle is usually stationed at Wairoa College, but was being repaired in workshop at Onekawa in Napier when it was stolen last weekend.
The Hawke's Bay District Health Board said the thieves must have been used a four-wheel-drive vehicle because the clinic is too heavy to be towed by a car.
The board's service manager, Claire Caddie, said it does not yet know how it will deliver dental services to young people in the town.
