Magnet Bay

Te Oka, New Zealand
🪨Rocks

Christchurch's best-known point: a long left over boulders in a small cove on the south side of Banks Peninsula, surfed since the early 1960s. Consistent in S swell; the walls get juicy and rides run 300 m or more. It works best on a S swell with N winds around low tide. Watch for: boulders, bull kelp.
