The cache is not at the above coordinates.
If you have never tried a puzzle cache before, give this one a go. It is super easy. The information you need can be found on one of the two monuments in the park at the posted coordinates.
Once you determine what day Captain Cook made his first landing at Waimea, you can complete the simple formula below:
Month, D(A) D(B) ,Y(C) Y(D) Y(E) Y(F)
The cache is located at N 21 57.ADF W 159 40.ABA
There is parking very close by or you can walk over from waypoint 1. Beware of muggles or the cache will disappear.
Please bring a pen.
A very big thanks to Hanapaa who agreed to look after this cache on my behalf.
