It was far from a one horse race though, with the 19-year-old catching Hurst at the halfway point of the 2.6km journey.
"Josh is one of the best open water swimmers in the world and has a huge future. So it was inevitable that he was going to catch me. At the end I was hoping we'd both catch a wave and body surf in, but it wasn't to be," Hurst said.
That meant hard yards right to the finish.
"We got to the last can and it was all on. We had to give it everything we had, I just happened to get a nice couple of swells towards the end," Hurst said.
The women's race was far more decisive, with Australia's Melissa Gorman once again too good for New Zealand's best, Cara Baker and Charlotte Webby.
"It was a little different to what I was expecting. Standing on the beach it looked quite calm, but once I got there it was quite choppy, but as an open water swimmer you have to adjust, and I did that successfully," Gorman said.
While both Hurst and Gorman are still someway down in the overall series standings, their wins mean they are now strong favourites to win the overall series and the $20,000 grand prize.
"$20,000 is a lot of money and it'll definitely help me out a lot back home, with my training and travel plans. So, I'd love to have a good race in Auckland, just like everyone, so it should be a cracker," Gorman said.
To be eligible for the $20,000, each swimmer must compete in a minimum of three of the six races. 100 points is awarded to each race winner, with double points on offer in the final round, the State King of the Bays on Auckland's North Shore on April 6.
