The coordinates will take you to the base of a transmission line pylon on the Skyline Walkway. At the above coordinates work out the following from the warning sign on the pylon
The final cache coordinates are S 41 1A.BCD – E 174 4E.FGH
A = Third number of pylon number
B = 5th number of telephone number
C = Third number of pylon number – 3
D = Number of letters in word below TAKAPU ROAD
E = Last number of pylon number + 5
F = 8th number of telephone number – 3
G = 3rd number of live wire volts
H = Number of letters in bottom right-hand word – 6
13/11/20: The cache has been moved to a new home about 10 metres from its original location. Subtract .011 from the South coordinates (BCD) for the new coordinates. The East coordinates are still close enough to stay the same.
The Hint has changed as well.
The final location of the cache is a short walking distance away.
