This is part of a series of caches around great Wellington hill climbs. You need to gather clues from each cache in the series in order to solve a final puzzle series, so make sure you take note of every piece of information you are asked to collect. You will need it for the final series.
The published coordinates will take you to a sign that gives you no information whatsoever. It is, however, a short distance from here to Welly Climbs: Waiwhetu Hills Prequel, which does contain information needed to find this cache. Make your way there and find the information.
To get to the final cache location, deduct AA from the South coordinates and add BB to the East coordinates of Welly Climbs: Waiwhetu Hills Prequel
check sum for all the South coordinates digits is 21
check sum for all the East coordinates digits is 35
The cache is a camo'd screw top container, with room for swaps. Please bring your own pen.
