The survey mark 1328

The bronze plaque for 1328 (16 Mount Eden SO
52129), on a wet dull day with strong camera flash
reflections.

Mt Eden marks the centre of the Auckland region, at least as far as surveying is concerned. Next to a somewhat non-standard trig beacon stands an obelisk marking the initial station for the triangulation of Auckland in 1872. One of the plaques on the obelisk commemorates this:

This obelisk was first erected by
Stephenson Percy Smith,
Chief Geodetic Surveyor,
on the 17th day of August 1872
as initial station for the triangulation
of the Auckland province, instituted by
Captain Theophilus Heale
Inspector of Surveys.
"Prudens Futuri"

Below that plaque is another commemorating the centenary of the foundation of the Auckland Provincial Surveyors Association, founded approximately seven years prior to the commencement of the triangulation of the region:

To commemorate the founding,
on 22nd June 1865, of the
Auckland Provincial
Surveyors Association.
This plaque was placed
by the Auckland branch
of the New Zealand
Institute of Surveyors
22nd June 1965.

Another face of the obelisk had two plaques, but one has been removed. The remaining plaque states:

This plaque is to celebrate the third century of
surveying in the Auckland area. In this coming
century, the Auckland branch of the NZ Institute of Surveyors will strive to contribute to the growth and prosperity of our region.

This historic monument was restored in March 2001 by the Auckland branch of the NZ Institute of Surveyors, in partnership with the 1998-2001 Eden Albert Community Board.

Cover for C5LG (Mt Eden No. 2)

There is also another survey mark on Mt Eden: C5LG (Mt Eden No. 2), hidden under a cast iron cover 43m east of 1328. The cover was easy enough to find, but it was a wet day so I didn't bother lifting the lid.
