Stewart Barclay: Adrift Tongariro on the new booking system set to manage Tongariro Crossing visitor demand - Heather du Plessis-Allan Drive

A booking system is being set up for the Tongariro Crossing.

The Department of Conservation says it's a plan to manage visitor numbers- it'll be free to book and not compulsory.

Tour company Adrift Tongariro co-owner Stewart Barclay says it's a trial for now.

"And it will be compulsory in a wee while, maybe next summer. It's a bit of a dry run test, really."
