This is an offset-multi cache on the site of the landfill of much of the rubble from the Christchurch earthquake events. The posted coordinates will take you to a man-made structure with a hanging six-pointed object. Each of the six pointers, three long and three short, points in a different direction.
There is a marker that will be familiar to geocachers hidden on one of the pointers that indicates the direction you will need to walk or bike to find the container, which is located 183m from the posted coordinates.
You are looking for a camouflaged 180ml Sistema container.
