State Highway two has reopened following a crash involving two cars and truck at the intersection with Wright Road in Aongatete.

The New Zealand Transport Agency says the incident is now clear, however there is heavy congestion from Katikati to Te Puna.

NZTA advises people delay their journey or use an alternative route.

Northbound traffic is advised to use SH29 onto SH24 to Matamata, then either SH26 to Paeroa or SH27 to SH2 Mangatarata for north.

Southbound should traffic use SH27 to Matamata and follow SH24 to SH29 to Tauranga, the NZTA says.
