I had another multi in Aranui Park, however I was told that the signboard required for the information was missing. While there we couldnt find the cache either so starting from scratch with new information to collect, this time from a plaque on a huge rock that wont disappear unlike the wooden sign and a new hide.
The cache can be found at S41 14.ABC E173 05.DEF
