Cache is not at the posted co-ordinates so do not go there. They are in the middle of the Waikato river and you will get extremely wet if you do so.
Adventure Labs
Geocaching Adventure Labs are a type of Lab Cache. They were originally developed to offer private or time-limited geocaches. Examples include business partnerships, Mega-Events, and other community events.
In 2019, Geocaching HQ extended the Adventure Lab experiment globally. A select number of geocaching organizations and at least 500 qualified geocachers were given the chance to create Adventures. These Adventures will remain active for at least six months, or potentially longer, for the community to enjoy.

To find this cache you will have to visit all locations of either
The Parana Park Lab Cache

or
Memorial Park Lab Cache

At each location, if you answer a question correctly, you will be given part of the final co-ordinates.
The final information supplied in each Lab Cache is the same so it is not necessary to complete both. But you might as well.
I hope you enjoy the walk around the area and then the short walk to the final.
The final is close to a major walkway so please use discretion. Muggles can appear at anytime and from either direction. Please ensure cache is placed back exactly as it was and is well covered.
You can validate your puzzle solution with
certitude.
