Part of the street is cordoned off while a scene examination takes place.
The police cordon is outside Wharenui School, near Blenheim Rd, beside Wharenui Swiming Pool and Sports Centre.
Five red and yellow soft jump packs can be seen open with masks, gloves and bandages at the intersection near traffic lights and on the footpath.
A police forensics tent is covering the section of road where the medical equipment and some blood could be seen on the ground.
Police staff are now inspecting the scene.
Neighbours in the area say they came outside in the early hours of this morning to see what was going on after hearing several loud noises followed by police sirens.
