The Ōmanawanui Track in the Waitākere Ranges is one of New Zealand’s premier coastal walks — nearly 3 km long, climbing about 373 m and taking up to 3 hours one way. The track crosses two steep peaks (the eroded remains of an ancient volcano) on the north side of the Manukau Harbour entrance, with cliff-edge sections and sweeping West Coast views from Whatipū down to Karekare. The track re-opened in recent years after a long closure under the Waitākere Ranges kauri-dieback rāhui placed in 2018.

About the Track
Ōmanawanui follows the ridgeline of the eroded northern rim of the ancient Manukau Volcano. The two main peaks crossed are Ōmanawanui (a low rocky summit with full panoramas) and the neighbouring ridge that drops down toward Whatipū. From the higher points you look directly down onto the wide black-sand expanse of Whatipū, the Tasman bar at the harbour entrance, and — on a clear day — north to Karekare, Piha and beyond. The track is well-formed but exposed: large sections sit on cliff edges with only the natural slope between you and the drop.
What to Expect on the Track
From the Whatipū Road end the track climbs steeply on built timber stairs through regenerating coastal bush, then opens onto the first peak. Between peaks there are short descents and re-climbs, with several lookout points that face directly out to the bar. The Whatipū end finishes on flatter ground crossing wetland boardwalk before reaching the car park. Most people walk it one-way and arrange a shuttle, or turn around at the highest peak (about 1 hr in) for a shorter out-and-back.
Kauri-Dieback Hygiene
Phytophthora agathidicida (the pathogen that causes kauri dieback) is the reason this track was closed for years. Cleaning stations sit at both trailheads — scrub all soil from boot soles, then spray with the disinfectant provided, every time you enter or leave. Stay on the boardwalk and stairs throughout, especially in the regenerating kauri sections. Take dogs elsewhere — they’re not permitted here for the same biosecurity reason.

Frequently Asked Questions
How long is the Ōmanawanui Track?
Nearly 3 km one way, taking up to 3 hours depending on pace.
How much climbing is involved?
About 373 m elevation gain, with roughly 2,400 built stairs across the route.
Is it a loop?
No — it’s point-to-point between Whatipū Road and the Whatipū car park. Most walkers either shuttle a second car or turn around at the highest peak for an out-and-back.
Are dogs allowed?
No — dogs are not permitted, partly because of kauri-dieback hygiene and partly because of native bird protection in the regenerating bush.
Is it safe for kids?
Older confident kids manage it, but the cliff-edge sections are exposed and unfenced — best for families with previous tramping experience together.
