Note: the posted coordinates are bogus, and show a good place to park at one of the reserve’s entrances.
The four other caches you need to find are:
Each container has two letter/number combinations inside the lid of the container. Take note of these to reveal the final coordinates for the Waiatarua Mystery cache, using the following:
S36° 5A.BCD
E174° 4E.FGH
At the time of cache placement, the cache contains a log notepad, pen, a trackable that is supposed to be in the USA, and some swag items. It is a black taped 1 liter rectangular Sistema container, covered with natural camouflage, and hidden in what should be a fairly obvious location when you get there.
The difficulty rating is based on having to find the other four first, and finding your way in. Note that it can be a little bit tricky to find a way to the physical location once you have worked out the coordinates especially with all the planting that's been done.
