@Journeyman I'd say it's here
Spot on, that exactly where it was. There is no off ramp at Puhinui Rd so the van driver saw the motorway backed up and thought they'd use the Cavendish Rd on ramp to leave the motorway. He joined the slip road that you can see on the far side of the on ramp and continued on his way. probably would have headed out to the airport before rejoining the southwestern motorway further up @ Mangere Bridge.
