Meridian Swim Ruataniwha 2026

Dive into the adventure at the
Meridian Swim Ruataniwha.

The ultimate open water swim on the sparkling turquoise waters of Lake Ruataniwha, right in the heart of the stunning Mackenzie Region!

Since making a splash in 2023, this event has already given back over $20,000 to local community groups – supporting everything from water safety programs to water-based activities across Twizel. Groups like Mackenzie Lakes Coast Guard, Twizel and South Island Rowing, St John, Twizel Swim Club, Land SAR, and the Twizel Community Patrol have all benefited – proving that every swimmer, sponsor, and supporter is helping the community thrive both in and out of the water.

Now entering its 4th year in 2026, Meridian Swim Ruataniwha has cemented itself as a must-do event on the southern swim calendar. And thanks to the Southern Swim Series – linking together The Ruby in Wanaka, The Whakatipu Legend in Queenstown, and of course, our very own Meridian Swim Ruataniwha – swimmers can take on all three and be in to win a spectacular spot prize worth at least $750 in 2026!

✨ Save the date: Saturday 14 March 2026 ✨
The first splash hits the water at 9:30am (final start times confirmed closer to the day). With three fun-filled challenges, there’s something for every swimmer:

🏊 The Top Hut Sports Bar & Bistro 500m – the perfect entry-level event for first-timers, social swimmers, or anyone keen to dip their toes into open water.
🏊 The Twizel/Mackenzie Four Squares 1500m – a great middle-distance swim for those who want to test themselves and feel the thrill of a challenge.
🏊 The Mt Cook Alpine Salmon 3800m – our premier endurance event, tailor-made for experienced open water swimmers and triathletes chasing their big goals.

With awesome spot prizes, a buzzing lakeside atmosphere, and the knowledge that your swim is giving back to the Twizel community, Meridian Swim Ruataniwha is more than just a race – it’s a celebration of people, place, and the joy of open water swimming.

🌊 New for 2026 – The Teams Category! 🌊

Swim Ruataniwha just got even more exciting – now you can race not just for yourself, but as part of a Team! When you enter, simply select if you’re swimming solo or lining up with your crew.

🏊 Two team vibes – pick your style:

• Social Teams – All about fun, friendship, and giving it a go! Gather your workplace buddies, swim club mates, or group of friends and take on any event together.

• Performance Teams – Serious speed and bragging rights on the line! Perfect for club rivalries or anyone chasing the title of fastest team in the lake.

⚡ How it works:

• Teams must swim the same distance event (but your workplace or club can have multiple teams across different distances).

• Make sure your team name is identical for all team members entering.

• A team needs a minimum of 3 swimmers.

• The fastest 3 times in your team are averaged to determine your result (Performance Team)

• ✅ No extra entry fee! Everyone just enters individually, and your results automatically count towards your team.

So, rally your squad, lock in a name, and dive in – because Swim Ruataniwha 2026 isn’t just about individual glory, it’s about team pride too! 💪
