Originally from England, Marsden-Mayer had been living in Ruapehu until he moved to Wanganui three months ago.
"I have done a lot of commissions and had exhibitions over that time but it was winning the people's choice award for my Kashin elephant sculpture in 2012 that has really put me on the radar."
NZ Sculpture OnShore is a biennial event held at Historic Fort Takapuna on Auckland's North Shore, with proceeds from each exhibition donated to Women's Refuge. It has raised over $1.34 million since 1994.
Exhibition curator Rob Garrett said in a radio interview that Marsden-Mayer seemed to have "cropped up out of nowhere" to win the award for his elephant sculpture.
The artist said his work was spread around the country and a couple of moa had just been dispatched to Christchurch.
"I don't count the number of pieces I use in a sculpture - I just add pieces until I get the look I'm going for.
"Most of my work is commissions so I have really enjoyed working on the whale and I hope it will earn me the people's choice award again this year."
NZ Sculpture OnShore runs from November 6-16. Marsden-Mayer's work can be viewed at www.animaldriftwoodsculptures.co.nz
