Welcome to The Metal Effect
We design and build custom Corten steel pieces right here in Cromwell, NZ.
Our work is crafted to elevate any outdoor entertaining space — from heavy‑duty BBQ fires and sculptural log pods to our stacked metal dice art and other signature creations.
Every piece is built tough to handle New Zealand conditions and look great year after year.

The Living Patina:
The Beauty of Corten Steel
Unlike ordinary steel that degrades, our Corten steel is designed to age gracefully. It develops a stunning, self-protecting 'living patina' that reacts to the Central Otago elements. This deep bronze-to-orange layer isn't just for looks—it forms a protective barrier that prevents deep corrosion, ensuring your piece lasts for decades without the need for painting or maintenance.
Your sculpture or fire pit will arrive in a raw or partially weathered state and will continue to evolve and deepen in character, making every piece truly
one-of-a-kind
ARTISTIC EVENTS
Art in the Park
2026
17th September 2026
Art in the Park will be held in November this year, instead of September. Last year one of Nigel’s pieces was selected for the People’s Choice Awards — and that piece went on to win. This year, another of Nigel’s works has been chosen for the People’s Choice selection: The Turning, a 3D maple leaf sculpture crafted from corten steel.
Art in the Park Auckland 2024
September 2024
We are getting a bit excited around here.
I have been invited to attend The Art in the Park at Eden Park Auckland, in September 2024. I have two sculptures that are coming with us. It will be exciting to see how people will react with my sculptures as well as seeing what others are doing. So many talented people out there. I feel very privileged to be doing this.

Wanaka A & P 2025
August 09 2024
We are starting some planning for the up and coming Wanaka A & P Show. Amongst or daily stuff we are doing. We are hoping to get some new items made and hopefully we will have a waterwheel again, may not be the biggest size but we know from past shows this has been a show stopper that young and old enjoy. So watch this space.
