NZ Transport Agency Waka Kotahi (NZTA) is advising road users to expect delays on SH20 between Puhinui Road and Cavendish Drive.
Due to a serious crash, the northbound Cavendish Drive on-ramp is closed, as well as the southbound service road between Puhinui Road and Cavendish Drive.
A detour for people heading north is available via Roscommon Road, Noel Burnside Road, Puhinui Road, then joining SH20 northbound via the Puhinui Road on-ramp.
Vehicles who would have used the southbound service lanes between Puhinui Road and Cavendish Drive can use the reverse of the northbound detour given above.
Vehicles headed further south can still use the Puhinui Road southbound on-ramp to join SH20 (just the service lanes are closed to Cavendish Drive).
NZTA thanks road users in advance for their patience.
