The centre of things
Over the summer I stayed with my mate in the Benneydale back country. One day, left to my own devices, I did a bit of tiki-touring. A few years ago my mate was based at Pureora, a few minutes east of Benneydale, so he was able to give me directions to a couple of places to go in the forest park. First stop was Pureora village itself – well, the half-dozen houses that now make up that community.
After the town I hit the dirt road in search for the ‘Centre of the North Island‘. A spot ‘discovered’ a few decades ago by a DSIR scientist who clearly didn’t have enough work to keep him busy. The plaque on the ‘monument’ (below) tells the story of how he worked it out.
The ‘monument’ itself was rather disappointing, though probably in keeping with the method of discovery. Call me fussy, but I couldn’t help thinking that if you wish to find the centre of balance for any geological formation, you really should take into account the three-dimensionality of the real thing, and not assume that the landmass is equally distributed.
I was reminded of a family holiday years ago when we visited the ‘Centre of New Zealand‘ in/near Nelson with its far more grandiose monument. I remember Dad asked us how they came up with that being the centre. I threw him a few ideas, none of which were right. He never did tell us.
Apparently the ‘real’ ‘Centre of New Zealand’ is in the Spooners Range near Tapawera (41 deg. 30 min S., 172 deg. 50 min E.), though this too was found via a gravity survey that took in Stewart Island, the North and South Islands, and the smaller inshore islands, but not the Chathams. The Nelson point was merely a somewhat arbitrary point for an 1870s survey project.
Besides gainfully occupying some surveyors or scientists for a few hours or days and being a nice bit of trivia, I’m not really sure what purpose these centres have. They do make for pleasant enough detours though, and on the way to the ‘Centre of the North Island’ you can do the much more pleasurable (and not terribly strenuous) walk to the summit of Mt Pureora, with its stunning views of the centre of the North Island.
