Bird watching

species have been recorded here. Some, like the Eastern bar-tailed godwit/kuaka are international migrants, making an annual journey from their Siberian breeding grounds for the southern summer feast. The wetlands also provide a vital refuge for rare residents, including the southern New Zealand dotterel/tūturiwhatu, marsh crake/koitareke, fernbird/mātātā and Australasian bittern/matuku

Kayaking and canoeing

At high tide or when the outlet is closed kayaks or small power boats can be used to explore the margins of Waituna Lagoon.

Situated within the Awarua-Waituna Wetlands complex, Waituna Lagoon is easily accessed and only 40 minutes (by car) from Invercargill city. The Waituna wetland can be accessed via walking tracks off the Southern Scenic Route via Waituna Lagoon Road and Waghorns Road. Access to the spectacular, white quartz beach is on an unmarked track off Waituna Lagoon Road.

Basic boat ramps are available at Moffat Road end and corner of Waituna Lagoon Road and Waghorn Road.

    About this place

    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 20,000 ha 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

    Access into the Awarua-Waituna 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. Before crossing the bridge turn left onto Awarua Bay Road and follow the road to a parking area at Muddy Creek.

    To reach feeding areas and roosts walk around the head of Awarua Bay and be prepared for some knee deep wading and estuarine mud in places. 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).At high tide or when the lagoon outlet is closed to the sea 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 for bird viewing over high tide (1 to 1.5 hours after Bluff tide time) and you should be prepared for knee deep wading, estuarine mud and exposed conditions.

    Bring binoculars or a telescope. Be prepared for variable weather in any season - take a wind and waterproof parka, overtrousers, hat, gloves and sunblock. 

    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.

    Do not light any fires when visiting Awarua Bay, Waituna wetland or Waituna Lagoon and coast. Even though by nature wetlands are wet they do burn very easily. In the past fires have swept through hundreds of hectares of the Awarua-Waituna Wetland and decades later the vegetation has still not fully recovered.
