Will it survive outside is the question I get more than any other, and it's the right one to ask. Not all outdoor art is truly waterproof. Here's what actually holds up to New Zealand rain, sun and salt, and how to choose a piece that still looks good in ten years.
Steel art doesn't soak up water the way canvas or timber does, but it's the finish that decides whether it lasts. A properly finished steel or aluminium piece shrugs off rain, UV and frost. A cheap coated or composite piece can rust, fade or peel within a season or two. So waterproof isn't just the material, it's how it's made.
Powder-coated steel and aluminium seal the metal under a baked-on colour that won't fade or rust in normal use. Marine-grade 316 stainless is the safest choice for full coastal exposure. Corten is made to weather into a stable rust that then protects the metal beneath. All three genuinely last outdoors here.
Two things I'd steer you away from for anything you want to keep. Aluminium composite is two thin metal skins over a plastic core, made for signage, and the layers can separate outdoors. Acrylic, or Perspex, is a plastic that fades, goes brittle and cracks in our sun. Neither is built for the long term outside.
Even the toughest finish has an easier life in a sheltered spot. A piece under an eave or on a covered patio will outlast one in full sun and driving salt wind, so factor the exposure in when you choose the finish.
Outdoor art is low effort. An occasional wipe, a fresh-water rinse near the coast to clear salt, and a yearly check of the fixings is all it needs. If a powder-coated edge ever chips, a dab of touch-up paint reseals it.

Properly finished steel and aluminium art is. It's the finish that matters: powder coating, marine-grade stainless and corten all handle rain, sun and frost. Untreated or composite pieces are the ones that fail.
Brushed marine-grade 316 stainless for full coastal exposure, with powder-coated aluminium and corten also coping well with salt air.
Not the right finishes. Powder coating is UV-stable so it holds its colour, and corten is meant to change into its patina. Cheap acrylic and printed pieces are the ones that fade.
Wipe it occasionally, rinse off salt near the coast, and check the fixings once a year. A chipped powder-coated edge just needs a dab of touch-up paint.
