You are looking for a regular size container, please make sure screw the lid firmly closed when you put it back and return it as you find it. Please be mindful of muggles.
The container is hidden near where a face has been carved into the stump of a tree beside a path that runs next to the Waikato river. The path leads away from the Hamilton Gardens, a popular tourist attraction. For those into other location based games, you will also find a Pokestop here.
