Art and science collide with the unveiling of a new Billy Apple® artwork

The full-colour framed canvas which now hangs in our Avalon office is the second collaboration between conceptual artist Billy Apple® and GNS Principal Scientist Cornel de Ronde.

Created as a companion to the stainless-steel plaque in the Tararua Ranges which marks the geographical centre of New Zealand’s Extended Continental Shelf(external link), Billy gifted the artwork to GNS to acknowledge all the hard work done to pinpoint the centre of New Zealand’s territory.

The project’s journey started a decade ago when the pair met through a mutual friend and became fascinated with each other’s work. In one discussion, Cornel told Billy about how GNS and NIWA had discovered New Zealand was sitting on a mass more than 20 times larger than the land we stand on today.

Billy was fascinated that 95 per cent of New Zealand’s extended continental shelf is underwater, which lead him to ask, “So where is the centre of New Zealand?”

Cornel knew this was a puzzle that GNS Science could help solve.

Data technician Jenny Black completed the mathematical equations in the quest to calculate the centre of New Zealand.

Imagine you wanted to balance the extended continental shelf on your finger; the centre is the point where your finger would rest

“This is a way of saying thank you for getting all this done. All I actually did was ask a simple question, but it’s really all Jenny Black. She’s a remarkable woman," Billy says.

Billy Apple® and the Centre of New Zealand | Art Meets Science transcript
It was a time in my life where  I was starting to collect art, 
and I heard of this chap he knew, Billy Apple,
and I thought, "Oh that'd be kind of cool, to meet." 
You know, Billy, I think was a bit intrigued  by what I did, was a bit unusual really,  
and I was intrigued by what he did, and  it kind of just went from there, I guess.
Then he told me all about - what's the right word? The extended continental shelf. 
The extended, extended continental shelf. And that, I found fascinating. 
You know like, you know what  that meant, and how large. 
I was absolutely in awe of the fact, that he said,
"You know, I think we're about the fifth  largest piece of land in the world".
Then one day, I said to him,  "Well, where's the center?" 
I don't know, because, why would I know?
Why would you want to know?
No, I didn't exactly, but I thought, 
"Okay, we could do that at  GNS, so we'll go find out".
Jenny Black, at GNS here, she did a fantastic job.
So, she delved into this, and it's  all done properly and mathematically.
This is a great conversation  that Billy and I will have about,
"You know, where is the center of something?" and  then, we talk about errors and all the rest of it.
So, mathematically, these three  choices are all acceptable. 
As it turns out, one of those three, more or  less lands on this track up on the Tararuas.
That was the preferred one,  mathematically, most correct.
So, as it turned out,  
never mind the fact of this incredible size  of this extended continental shelf area,
you can actually find the  center, just out of Carterton.
I mean, what are the odds?
So, what we have at the top, is really no  different than a signpost, that implies that  
600 meters is a roundabout, or you know whatever.
It's closer than that, actually.
Well, well whatever it is,  I thought it was 600 meters.
No, I don't think it's quite  that far, but it doesn't matter. 
Much closer, 200, I think.
200 meters, even better still.
David Titchener is a great guy,  young guy, and he was all keen.
He thought, "What a wonderful project".
Helicopters, concrete, all  had to be helicoptered up,
and he and I and Jenny, we dug out the thing, 
and did the boxing, and concreted  it in, and the rest is history.
It is an engraving in marine stainless steel.
Pick it up to stand with your  legs apart, right over the point, 
you know, so you literally are in the center.
I feel extremely privileged to be able to  work, and be able to have a conversation,  
and then out of it, to come a work from,  working with someone like Cornel at his level,  
and to entertain my question seriously, from my  point of view, and to achieve what we've done.
It's a hard question, and it's been answered

I feel very privileged, and [the canvas] is a souvenir of the work [GNS] did; they did a tremendous job with all the helicopters they had to get in and getting the plaque in
