The Western Bay of Plenty District covers 212,000 hectares, which is about three-and-a-half times the size of Lake Taupo.
The 1,020km of local roads and 198km of state highway in the District are managed under a performance based contract.
Of the 1,020km of local road, approximately 180km is unsealed. The average cost of seal extensions (including design and consent costs) is $450,000 per kilometre.
The current 'One Network Maintenance Contract', like its predecessor Performance Based Contract (PBC) 01, is unique in New Zealand in that has very clear, measurable outcomes.
A contracting alliance, which includes Opus Consultants and Downer, collectively known as Westlink, manages the contract.
Savings under the contract, are allocated to additional community roading projects, such as seal extensions.
