Mainland Island Restoration Organisation (MIRO)

Location of MIROMIRO is a volunteer group who work in partnership with Greater Wellington Regional Council (GWRC) in the East Harbour Regional Park (EHRP) in Eastbourne.


MIRO is committed to restoring the forest and lakes ecosystem of EHRP. Central to this is the elimination of animal pests - possums, rats and stoats and the replanting of native flora. Control of these predators will allow vulnerable flora and fauna to flourish again and allow the reintroduction of species lost to the Park.


On the eastern shore of Wellington Harbour, sited between the urban areas of Eastbourne and Wainuiomata. .


The Northern forest block consists of 2000ha of lowland beech and broadleaf forest with an ancient Rata forest.  The Parangarahu Lakes area in the south of the Park surrounds the nationally significant freshwater lakes Kohangatera and Kohangapiripiri . This area of 360ha is predominantly regenerating scrub.

Management history

2004 Wellington Regional Council took over management of EHRP, set up a 60 km network of possum kill traps and MIRO provided volunteers to service the traps.  A mainland island of 350ha was set up within the northern forest block to intensively trap rats.

2005 Plant Nursery set up and in 2007 the first 800 trees were planted at Parangarahu.
