Jono Ridler Hits Halfway Mark in Swim4TheOcean

Open water marathon swimmer Jono Ridler has hit the halfway mark of Swim4TheOcean – his world-record swim attempt from North Cape to Wellington with a call to end bottom trawling.

From here south, the Swim4TheOcean mission is leaving behind a coastline with safe harbours and boat ramps – heading into new territory where few safe harbours exist and beaches and bays are often exposed and only viable access points in certain conditions. East Cape itself will require a strategic approach with tidal flow and currents expected to compress around the eastern tip of Aotearoa New Zealand.   

Reaching 694km off Waihau Bay, just before Cape Runaway and East Cape marks an extraordinary endurance milestone in one of the longest staged ocean swims ever attempted.  

Ridler is reminding people why he’s doing it and how they can show support. “This swim has never been done, and it’s already pushing me  mentally and physically like I’ve never experienced before… but that’s the point. I’m swimming to shine a light on ocean health and I’m asking people to get behind Swim4TheOcean by signing our call to end bottom trawling at swim4theocean.org.   

“One of the most urgent things we can do is to transition away from destructive bottom trawling. I’ve met people on beaches all the way from Waikuku in the far north to here at Waihau that agree, and support what we’re calling for.  

“It’s what keeps me going day after day and I’m determined to take that message and at least 50 thousand signatures with me as I get to Wellington about six weeks from now.”   

Already 13,712 have signed the call which asks the New Zealand Government to end bottom trawling on all seamounts – at home and in the high seas by the end of 2027 – and to activate a quick transition away from bottom trawling entirely. 

In six weeks Ridler has free-styled 694km of exposed coastline, spending more than 235 hours in the water. 61 swim legs in total – battling currents, changing sea states and the physical toll of back-to-back shifts up to six hours  long, he has already covered a distance few swimmers in the world have ever achieved in a single campaign. 

But Swim4TheOcean is about more than distance. It’s a mission to ignite New Zealanders around the importance of ocean health and recent independent research shows strong public backing for change. 78% of New Zealand adults (3,019,000 people) support a ban on bottom trawling in the South Pacific high seas. And 73% (around 2,825,000 adults) believe commercial fishing practices need to change.* 

Since leaving Waikuku Beach at North Cape on 5 January,  Swim4TheOcean  has traced a path down the east coast of the North Island – past remote  headlands, marine reserves and busy coastal communities. Ridler has encountered orcas, seabirds, sharks, dolphins and schooling fish, and been welcomed ashore by locals gathering on beaches, paddling out in kayaks, coming out in boats and turning out at community stopovers. 

The scale of his effort is matched by the logistical challenge and the old adage  ‘everything is harder on water’ rings true for the Swim4TheOcean crew. A seven-strong team are supporting Ridler’s swim attempt across  boats and  land – the on-water team watching his every stroke, monitoring conditions  and keeping him fuelled.  

For now, Ridler is focussed on celebrating the halfway milestone.  

He’s projected to arrive in Wellington in late March or early April. When he does Swim4TheOcean will carry a clear message to decision makers: commit to ending bottom trawling.
