Motorists will notice an increase in toll road pricing this weekend.

From Saturday, July 1, the price of using toll roads will rise by 20-40 cents.

A Waka Koathi spokesperson says although roadside signage may be changed before July 1, the pricing will not change until 12.01am on July 1.

The increase will be for cars, motorcycles and light commercial vehicles on Tauranga Eastern Link, SH2, and Tauranga Takitimu Drive, SH29, and Auckland's Northern Gateway, SH1.

Trucks, buses and other heavy vehicles will be met with a 40 cent increase.

"The legislation enabling road tolling in New Zealand allows for tolls to be adjusted annually in line with increases in the Consumer Price Index," says a Waka Kotahi spokesperson.

"The changes coming into effect on July 1 are the first increases to tolls in over four years, with the last adjustments made in March 2019.

"Waka Kotahi has kept the toll increases below average CPI over the period since the last increase, while ensuring toll revenues will continue to enable the timely repayment of debt."
