A vehicle has lost a load of metal and damp concrete on State Highway 2 this morning, between the intersection of Welcome Bay Rd and the Affco meat works at Rangiuru.

Senior Sergeant Ian Campion warned motorists to take extreme care through this area and wash their vehicle upon arrival at their destination, to avoid damage to paintwork.

The majority of the spill fell on the eastbound lane, headed towards Te Puke, with lesser amounts in the westbound lane, headed towards Tauranga.

Mr Campion said it appeared a heavy motor vehicle had lost the load about 8.15am, possibly due to the tail gate coming unlocked.
