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 $25,000 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.

In 2026, Swim Ruataniwha provided funding to support an Adults Learn to Swim program conducted by Health Bothy.

Now in it's 5th year, 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, Clyde Open Water Swim and of course, our very own Meridian Swim Ruataniwha – swimmers take on three of the four races and be in to win a spectacular spot prize worth at least $1000 in 2027!

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 Mackenzie Four Square 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.
