Tauranga Eastern Link Toll Road eastbound lanes between Pāpāmoa and Paengaroa will be closed for part of Saturday.
They will close between 5.30am and 1pm for the cycle-leg of the Tauranga Half Triathlon, which is part of the Mount Festival of Multisport.
This will be the fourth year the event has used the toll road lanes for the cycle leg, NZ Transport Agency Waka Kotahi said in a statement.
The alternative route for motorists during this time is via Te Puke Highway.
