An oil slick and blobs of old oil has washed up along about 10km of the Horowhenua coastline - leaving beach users shocked and disgusted with the culprit.
About 11am on Monday, the Horowhenua Chronicle received a call from a distressed resident who had been out walking on Foxton Beach, north of the surf club.
At first glance, it appears like black sand but, as you walk closer, an oil slick has streaked along the sand and blobs of pebble-sized oil is spread along the beach at high tide between south of Foxton right through to Himatangi Beach.
A short time later, a team of about 20 Horizons staff were mobilised to respond to the spill, closing the beaches to vehicles.
