      Nature and conservation

      This is one of the three sites that make up the national Arawai Kakariki wetland restoration programme.

      This site includes four major wetland types: coastal lagoons (notably Waituna Lagoon), freshwater swamps, extensive peatlands, and estuaries. Each ecosystem is unique and maintained by different ecological processes.

      It is visited frequently by many different trans-equatorial migrating and wading bird species, as well as threatened plants and insects including sub-alpine species.

      Awarua Bay
      • Most years it holds the second highest number of waders and a greater number of species than other sites in Southland. 
      • It attracts rare visitors to New Zealand such as Siberian tattler, greenshank and sanderling. 
      • Most migratory waders are present only from October to late March but some of the more common species are present through the winter.
      Waituna Lagoon

      The lagoon and the surrounding wetlands area was one of the first in New Zealand to be officially recognised as a wetland of international importance.

      The 3,500 ha wetland, known as the Waituna Wetland Scientific Reserve, was listed as part of New Zealand’s obligations when signing the Ramsar Wetland Convention. This international convention promotes wise or sustainable use of wetlands and recognises wetlands of international importance.

      The lagoon is periodically open to the sea and its brackish waters are an important habitat for wildfowl, native fish and trout.

      The surrounding wetlands have some unusual plant associations, like the cushion plant Donatia, which normally grows in subalpine areas. In the cold, peaty conditions low growing moor-like vegetation dominates. Manuka and turpentine shrub overtops wire rush and tangle fern. Native orchids and the insectivorous sundews and bladderworts, are common. The southern shore gentian flowers in profusion in late summer along the shingle banks of the coast.

      History and culture

      The local Maori people Ngai Tahu traditionally utilised the wetlands as a food source, eg fishing native eels, and for other resources.

      Since early Maori settlers arrived in Southland the Waituna Lagoon area has been a focal point for collecting food especially kai moana. In recent times local families have also used the lagoon and surrounding wetlands for recreational hunting and fishing. 

      Getting there

      Awarua Wetlands.
      Awarua Wetlands

      Access into the Awarua Wetlands area is difficult although you can view some of the cushion bog and other communities near the road end at the head of Awarua Bay located approximately 20 km south of Invercargill.

      To go bird watching at Awarua Bay travel towards the Tiwai smelter from Invercargill until the bridge over Awarua Bay. Turn left and follow the road to a parking area at Muddy Creek.

      To reach feeding areas and roosts walk around the head of the bay and be prepared for some knee-deep wading. Although you can see birds at any stage of the tide, the best viewing is gained over high tide (1 to 1.5 hours after Bluff).

      Waituna Lagoon is located 40 km south east from Invercargill at the end of Waghorns road and can be reached by road at several points. To get to the outlet it is necessary to walk along the coast from Waituna Lagoon Road (1.5 hours) or along the beach after crossing the head of Awarua Bay (2.5 hours). At high tide or when the outlet is closed kayaks or small power boats can be used to explore the margins of the lagoon.

      Know before you go

      It is best to visit the head of Awarua Bay over high tide (1 to 1.5 hours after Bluff) and you should be prepared for knee-deep wading and exposed conditions.

      Access into the peatlands is difficult and there are many areas where the surface may give way. Always leave your trip intentions (return time, planned route, party numbers etc) with a reliable person. Remember to check in on returning.
