Every morning when I arrive at the Porirua Park & Ride to take the train into the city, I look at all the great hiding spots and the massive amount of parking and wonder why there isn't cache here. Well, now there is. Watch out for muggles!
You are looking for a small plastic container containing a log book and pencil.
For your own safety, please approach this cache from the parking lot and not from the motorway off-ramp. It is much safer to approach from the parking lot (the entrance waypoint is provided).
To get to the car park by car, get yourself onto the elevated roundabout (Mungavin Interchange) and take the northbound exit as if you were heading towards Paraparaumu. Just before the on-ramp merges onto the motorway, take the exit on the left where the blue sign says "Railway Station".
