Daily Photo – Revisiting Dunedin’s St Clair Poles

There is a particular kind of optimism that belongs to the early settlers. They arrived at the bottom of the world, stared up at a mountain range that appeared designed specifically to prevent travel, and decided there must be a way through. They ventured into unmapped country searching for gold, launch small wooden boats into rivers no one has successfully navigated before, disappeared underground into cave systems simply to discover where they lead, or stood on a wild and exposed coastline facing the Pacific Ocean and think, yes, this seems like a perfectly reasonable place to build a settlement.

At some point in the nineteenth century, somebody looked at the stretch of coast that would become St Clair and came to exactly that conclusion. The difficulty was that nature had plans of its own. Standing on the Esplanade today, watching surfers drift beyond the breakers and families wander along the promenade with coffees in hand, it’s difficult to imagine the coastline as anything other than permanent. Yet for much of its history, St Clair was engaged in a long and often unequal struggle with the sea. The ocean would advance, people would respond, and then the ocean would advance again.

The first attempts to hold the coastline were charmingly optimistic. Timber walls were built, only to be destroyed. Stone walls followed and met much the same fate – in one case, a substantial wall survived for little more than two years before being swallowed by the sea. Another replacement was constructed at considerable expense and promptly suffered a similar fate and by 1890, after years of effort and expenditure, much of what remained was little more than wreckage scattered along the western end of the beach.

This was not simply bad luck. Geography was partly to blame. The shape of St Clair Point creates a complicated and often destructive wave environment. Storms arriving from the south-east are concentrated and redirected in ways that can be remarkably unforgiving. When the protective walls failed, the sea did not merely reclaim a strip of sand. Water pushed inland and contributed to a series of major floods that spread across South Dunedin. To residents living there at the time, the beach was not a recreational asset, it was a very real threat.

Eventually, around the beginning of the twentieth century, a different approach emerged. Instead of attempting to stop the ocean outright, engineers began looking for ways to work with the natural movement of sand along the coast. Their solution was the construction of groynes, heavy timber structures extending out into the surf. The idea was simple enough: trap sand moving along the shoreline and allow the beach to build itself naturally. For a time, the plan worked remarkably well. The beach widened. Sand accumulated. The coastline appeared more stable yet anyone familiar with the sea knows that victories are often temporary. Severe storms returned in the years before the First World War and reminded everyone that the ocean had not surrendered. The response was the construction of the concrete seawall that still forms the backbone of the Esplanade today, together with a new generation of timber groynes built from hardy woods including kauri, tōtara and Australian blue gum.

One of those structures would eventually become something rather unexpected. When it was first built, nobody would have imagined it becoming a local icon. It was simply infrastructure. A practical solution to a practical problem. Yet over the decades the groynes became woven into the visual identity of St Clair. They appeared in family photographs, postcards and later in countless social media posts. Generations grew up with them standing out in the surf, as familiar a part of the beach as the seawall itself.

Following reconstruction work in the 1950s, the groynes helped create what many remember as the golden years of St Clair Beach. Through the 1960s, 1970s and much of the 1980s, wide stretches of sand extended across the shoreline. For many Dunedin residents, this became the St Clair they knew best. Summer days seemed endless, and the beach appeared fixed and unchanging. Of course, coastlines rarely remain fixed for long. The sea is patient. Decades passed. Timber weathered. Marine borers tunnelled through hardwood piles. Winter storms loosened planks and broke supports. Slowly, almost imperceptibly at first, the structures began to disappear. What had once been substantial coastal defences were reduced to weathered remnants protruding from the water. By the early 2020s, only a handful of poles remained until eventually there was one.

For a surprisingly long period, a solitary timber post stood isolated in the surf. It was no longer performing any meaningful engineering function. It simply existed, stubbornly resisting the waves that had spent more than a century dismantling everything around it. There was something strangely moving about that final survivor. It had become less a piece of infrastructure and more a monument to persistence, both human and natural.

When it finally vanished beneath the waves in July 2022, it felt like the closing line of a much longer story.
