Emergency services were called to Southbridge-Leeston Road, near the Pooles Road intersection, at about 2.20am after a vehicle had rolled.
One person was critically injured, while another sustained moderate injuries.
Both were rushed to Christchurch Hospital.
The road was initially closed as emergency services and the Serious Crash Unit responded, but it has since re-opened.
