This is not part of the "name the trig" competition per se, although I am after the name of this trig, or at least the location of it. If indeed it is a trig station!
I visited this site around 2005 (that's me casually attached to the structure) and now cannot recall exactly where it was - except that it is betwixt Hokitika and Haast along the West Coast highway and in an easy access carpark/rest area. I am sure it is a monument in recognition of the Centenary of Surveying in NZ and thought that it was also a trig station or at least a geodetic mark. However, I cannot seem to find it via the LINZ geodetic database. Can anyone clarify for me where it is and possibly if it is a trig/geodetic mark? Ta.
