Maraetai Drive Reserve is a coastal nature preserve at 161 Maraetai Drive in Maraetai, part of Manukau City on Auckland's eastern coastline, and it holds a solid 4.7 Google rating. Details on access and facilities are on Auckland Council's parks pages.
Good coastal reserves do quiet but important work: holding dune lines together, giving shorebirds room to nest above the high-tide mark, and keeping pōhutukawa and coastal scrub standing so the shoreline keeps its character. Visitors get the most from one by timing a walk to the tides, since low water opens up firm sand and rock pools, and by keeping to formed paths, as dune planting is fragile. Regulars tend to favour early mornings and weekday evenings, and check signs for dog rules, which change from beach to beach.
Set on the Pohutukawa Coast, Maraetai Drive Reserve makes an easy stop when you're out Maraetai way, with the beach and village a short stroll off.
