 After the army had left, the area was turned into a reserve again, though the New Zealand Navy kept an area around the summit for a training school.Since the Navy school left the summit area in 1996, the Department of Conservation has administered the area as a reserve, which provides for beautiful walks along the waterline or onto the summit with good views of Rangitoto Island and Auckland due the prominent height of the hill.Also popular are exploratory forays to the gun emplacements and into the tunnel system, which is open to the public to a substantial degree, though torches are needed to explore it.
