Site Overview

The Wellington south coast holds several historical shipwrecks in deeper waters, including the Devon steamer, the City of Newcastle, and the Oanui, all of which offer challenging and rewarding diving for experienced wreck enthusiasts. The wrecks lie at depths of 25 to 35 metres in the exposed waters off the south coast, where the Cook Strait currents and ocean swells create conditions suitable only for advanced divers with strong current management skills. The Devon is a steamer wreck that lies scattered on the bottom, its boilers, hull plates, and structural fragments encrusted with decades of marine growth that have transformed the metal into thriving artificial reef habitats. The City of Newcastle and the Oanui are similarly scattered, with key features including anchors, portholes, and structural elements that reward systematic exploration. The deeper depths and exposed location mean that these wrecks receive far fewer divers than the accessible navy frigates closer to shore, preserving the historical integrity of the sites and providing a wilderness wreck diving experience. Blue cod patrol the surrounding reef, while crayfish shelter beneath hull plates and moray eels occupy the darker spaces between wreck pieces. The combination of historical interest, challenging conditions, and remote wilderness atmosphere makes the Wellington south coast wrecks an adventurous destination for experienced wreck divers seeking deeper exploration beyond the popular navy frigate sites.

Dive Briefing

"The dive begins at the first wreck site after careful assessment of current and swell conditions. Descend to the scattered wreck field at 25 to 30 metres, where hull plates, boilers, and structural fragments are visible on the rocky and sandy bottom. Follow a systematic search pattern, identifying key features including anchors, hull plates, and scattered structural elements. The wreck pieces are encrusted with sponges and marine growth that have colonised the metal surfaces over decades. Blue cod patrol the surrounding reef area, while crayfish shelter beneath hull plates. Moray eels occupy the spaces between wreck pieces. The strong Cook Strait currents require careful time management and constant awareness of the tidal conditions. The return follows the shallower wreck pieces at 20 to 25 metres. The safety stop is conducted in shallower water with careful monitoring of current conditions. The wreck pieces are encrusted with sponges and marine growth that have colonised the metal surfaces over decades since the sinkings. Blue cod patrol the surrounding reef area while crayfish shelter beneath hull plates and scattered structural elements throughout the wreck field."
