Styled in similar vein to GCRBKZ 'In Transit', you'll need to use the photos to find the cache, which is on Puketutu Island. Most of the island is privately owned - do not trespass onto private property or the access road to the greenwaste operation.
Pictured below is WP1, a large basalt rock marked at some time as an unofficial survey point, with coordinates for the final hidden underneath. The other two photos (taken at low tide) are views from the rock to help you pinpoint its location.
Access to WP1 and the cache is a good walk (but easy by bike), starting from the carpark coordinates given. Please, no spoilers in your logs to 'help' other searchers
