The NZ Transport Agency is urging Auckland motorists to plan ahead and allow more time for their journey as major road works, record congestion rates and rolling bus strikes loom.
March is reportedly one of the busiest months for traffic each year, with vehicles clocking up to 12.4 million kilometres every weekday, an extra 400,000km more than most other months.
Waka Kotahi NZTA's Auckland operations manager Rua Pani has warned motorists to make allowances.
"Plan your journey to avoid morning and evening peak times if possible. Leave earlier or delay your journey until after the peak. Travelling in off-peak hours helps avoid congestion and delays.
"If you have to travel in peak time, allow more time for your journey, or leave the car at home. Travel by public transport, walk or ride. It's good for your health and the environment.
