Miranda Shorebird Centre manager, birder and author, Keith Woodley has welcomed the latest addition to the conservation estate on the Firth Of Thames.
The Government has purchased about seven hectares for $250,000 in order to protect the area's Chenier plains - a series of ridges made up of sand, shell and gravel.
The site also contains wetlands with a healthy population of the threatened plant Maori musk and habitat for native species such as grey duck, South Island pied oystercatchers, grey-faced heron and pied stilt.
Mr Woodley said it was good news.
''Anything that helps to conserve habitat down here is to be welcomed.''
