Opening Splash 2025

Captain Arthur Wakefield stood on the shores of Nelson in 1841, raising the flag that would define the future of this settlement, a site later marked by the firing of a weekly time gun on Britannia Heights to synchronize the lives of the early settlers. Today, as you prepare for the Opening Splash, you are tracing the maritime heritage of Tasman Bay, entering waters that have tested navigators for nearly two centuries. The 2000m course, which begins at Tahunanui Beach, offers a clear view of the complex geography that once dictated the survival of early vessels. As you swim toward the finish at the Nelson Yacht Club, your line of sight naturally drifts toward the notable Fifeshire Rock. This jagged formation serves as a silent reminder of the ship Fifeshire, which carried the region’s first settlers in 1842 before meeting its end on these very rocks—a disaster that forced a fundamental restructuring of the harbor entrance in 1906 to ensure safer passage.

The landscape from the water

Navigating the bay, you are surrounded by markers that reach far beyond the shoreline. To the north, the elevation of Botanical Hill features a geodetic monument marking the 'zero, zero' point established in the 1870s, a vital reference for the first surveyors who mapped the entirety of New Zealand from this high ground. While you push through your stroke, you might also spot the silhouette of Haulashore Island. Formed in 1901, the island has a peculiar ecological history: it became a refuge for rabbits, which eventually led to the introduction of ferrets in the 1960s in an effort to manage the population. The environment here is defined by the 13-kilometre-long Boulder Bank, a natural barrier formed by rocks transported south from Mackay Bluff, creating the sheltered water that makes this swim possible. If you find yourself craving a follow-up challenge in these same waters, The Big Tāhuna takes place just six days later, offering a different pacing for those committed to the season. The event, organized by the Nelson Triathlon & Multisport Club, balances this rich history with a modern, accessible format, inviting swimmers to experience the same currents that have shaped the region’s history since the days of the Waitaha people and their early argillite quarries.
