Part of the Twin Coast Cycle Trail is being used by motorists after an access gate was sawn off.
Cyclists riding a 500m section of trail between Opua and Kawakawa are having to dodge cars after locals cut through a heavy steel gate and removed boulders. Motorists are getting onto the trail from State Highway 11 opposite Opua's industrial park.
The Far North District Council covered the railway line with gravel earlier this year so it could be used as part of its coast-to-coast cycleway. It is just wide enough for a small car.
The motorists appear to be mainly recreational fishers reluctant to walk 500m from the highway, but the dilemma facing the council is that the trail is also used by a family without suitable road access to get a sick child to medical appointments.
Council spokesman Richard Edmondson the poor state of Te Raupo Rd, a private road near Rigden Rd, meant some residents and fishers had been driving on the cycle trail. Vehicle access had been blocked by a gate and boulders but they had been removed.
