What Wetsuit Do You Need to Surf New Zealand?
What Wetsuit Do You Need to Surf New Zealand?
New Zealand is 1,600 kilometres from top to bottom. That's roughly the same distance as London to Athens, or Los Angeles to Seattle. And the ocean temperatures at either end tell very different stories.
Nowhere in New Zealand is further than 170 kilometres from the sea — and in many places, the mountains come right down to meet it. It's not unusual to surf a wave with snow-capped peaks watching over you. Wherever you are in this country, the ocean is close, and it's rarely what you'd call warm.
With the WSL in Raglan right now and surfers from around the world on our shores, we thought it was worth answering the question we get asked more than any other: what wetsuit do I actually need to surf New Zealand?
The answer depends entirely on where you're surfing. Here's what you need to know, region by region.
Shipwreck Bay, Northland — around 20°C
The far north is New Zealand's warmest water. In May you're sitting around 20°C — a Max 2/2 Ultra Chest Zip Steamer is plenty. Flexible, light, and comfortable for long sessions. This is as close to tropical as New Zealand gets.
Gisborne — around 17°C
Step south and the water cools noticeably. Gisborne sits around 17°C in May. A Max 2/2 Ultra Chest Zip Steamer is still workable, but if you run cold or you're planning longer sessions, step up to a Max 3/2 Ultra Steamer. You'll be glad you did.
Raglan, Waikato — around 17–18°C
The home of this week's WSL event. Water is sitting around 17–18°C right now. The Max 2/2 Ultra Chest Zip Steamer is your go-to — the Zirconium lining and Titanium Alloy Alpha reflect your body heat back to you, increasing heat retention by 40%, meaning you stay warm well beyond what the water temperature alone might suggest. If you run cold, step up to the Max 3/2 Ultra Steamer. Either way, don't be fooled by the numbers — the wind chill at Manu Bay has a say too.
Taranaki — around 16–17°C
A step colder again, and that exposed west coast wind makes itself known. The MAX Ultra 3/3mm Steamer is the right call here — the consistent thickness through the arms and legs makes a real difference when you're sitting waiting for sets.
Dunedin and south — around 13–14°C
Now we're getting serious. This is where you want the MAX Ultra 4/3mm Interchangeable. The interchangeable hood system gives you two bibs — one with a hood for mid-winter, one standard bib for shoulder season — making it one suit that covers most of the year. Quality neoprene matters here. A poorly sealed, petroleum-based suit will let water in and rob you of warmth fast.
The Catlins, Southland — 12–15°C
This is where New Zealand water earns its reputation. The MAX Ultra 4/3mm Interchangeable is your suit. Some brands sell a 5/4/3 for these conditions — but here's the thing. One of our own customers put it best: "I'm not sure if it's the material, titanium lining or sizing, but it is so much warmer than other 4/3 wetsuits I have used in the past — just as warm as my last 5/4."
That's Yamamoto limestone neoprene doing what cheaper rubber can't. Yamamoto's closed cell structure absorbs just 2% of its weight in water, compared to 30% for petroleum-based neoprene. A cheaper suit gets heavier and colder as your session goes on. Ours doesn't. Add boots — non-negotiable down here.
Why does the material matter so much?
Cheaper suits add millimetres to compensate for inferior neoprene. Yamamoto doesn't need them. With 30% more insulating air cells than petroleum-based rubber and a Titanium lining that reflects your own body heat back to you, a Seventhwave suit keeps you warmer at the same or lesser thickness — and stays that way throughout your session, not just the first ten minutes.
One of our customers has been wearing his 3/3 since 2017 — eight seasons and still going. That's what Yamamoto limestone neoprene built right actually means.
We've been handcrafting wetsuits from Yamamoto limestone neoprene since 1987 — long before the big brands caught on. If you want to know more about the material itself, read our Yamamoto blog here: seventhwave.co.nz/blogs/library/our-neoprene
