Porters Pass is a mountain pass at an elevation of 939 m (3,081 ft) above the sea level, located in the Canterbury region of New Zealand's South Island.
The road over the pass, on its route from Springfield to Cass, is asphalted. It’s called State Highway 73. This road is usually open all year, but it can be closed anytime when the access is not cleared of snow. The pass was named in 1858 by the Porter brothers who were farming nearby.
