Karehana Park is a popular community park in the seaside suburb of Plimmerton, Porirua. It has a pétanque court, a rugby goal, a paved pathway around the outside, a stream running through it, and a lovely playground with "roads" in it, so children can learn the rules of the road nice and early.
The cache is a quick walk-and-grab, though please do note that this is an extremely high muggle area, with lots of visitors to the park, and the back gate of everyone's houses open on to the park. Please bring your own pen, and re-hide the cache carefully. Enjoy the park!
