A popular walkway at Blue Spring near Putāruru in South Waikato will be closed for at least a year.
About 70 per cent of bottled water in New Zealand comes from the spring and the crystal clear stream is a popular spot for visitors.
South Waikato District Council said a rockfall in June made Te Waihou Walkway impassable from Leslie Rd.
Visitors had been using the State Highway 28 entrance to the walkway, but this had caused an overflow of cars and significant pedestrian safety issues on the busy highway, said council acting executive manager - delivery Shane Anderson.
