Stretching 4.7km across Mornington, Roslyn, Māori Hill, Woodhaugh and Opoho, the Town Belt provides a green cloak of native and exotic bush that separates the inner city from the outer suburbs.

In the north, the Town Belt connects directly with mostly native forest in Opoho Creek and Ross Creek, and to larger expanses of forest on the flanks of Signal Hill, Mount Cargill, and Flagstaff.

In 2006, an ecological assessment of the Town Belt recorded 22 bird species inhabiting the area. The bird species were split evenly between native and exotic, with silvereyes and the nationally threatened kererū the most common birds seen.
