Auckland's motorway network will face 48 overnight road work closures next week - including key routes to the airport.

The motorway improvements are scheduled from June 16 to 22, with closures set to begin at 9pm and be finished by 5am - unless otherwise stated.

The NZ Transport Agency overseeing the works is urging motorists to plan their Auckland night journeys ahead using the live updated Traffic Map webpage.

Of particular inconvenience, will be the closure of Puhinui Rd (SH20B), which is one of only two routes into Auckland Airport.
