Which Beaches Can You Find Pounamu?
Pounamu, New Zealand's precious greenstone, is one of the country's most treasured natural taonga. But here's the crucial fact: you won't find it on every New Zealand beach.
Pounamu occurs almost exclusively along the West Coast of the South Island, in a region known as Te Wai Pounamu, the waters of pounamu. This narrow strip of coastline, carved by ancient glaciers and fed by powerful West Coast rivers, is the main place in New Zealand where this nephrite jade naturally washes up on open beaches in collectible quantities. A smaller, geologically distinct source of pounamu, bowenite, also occurs near the entrance to Milford Sound in Fiordland.
Understanding where pounamu washes up, and why, matters whether you're planning to search for it yourself or simply want to understand the geology and cultural history behind it. This guide covers the main beaches, how to identify genuine pounamu, when to go, and the rules around collecting it.
The Main Pounamu Beaches of the West Coast
Hokitika is the most well known and accessible pounamu beach in New Zealand. The Hokitika River drains directly from the high country where pounamu-bearing rock is abundant, and its flow continuously washes stone down to the beach, making Hokitika a genuine hotspot for pounamu hunters. The town has embraced its greenstone heritage: local shops, galleries and the Hokitika Museum celebrate the stone's history, and the beach itself welcomes visitors keen to try their hand at fossicking.
Further along the coast, Greymouth, at the mouth of the Grey River, is another productive spot where pounamu regularly turns up after heavy rain or a high tide. Haast, near the Otago border, sits close to the confluence of several rivers that drain pounamu-rich mountains, making it another reliable hunting ground. Some pounamu also appears on beaches further south towards Fiordland, though the terrain there is remote and harder to access. Each stretch of coast has its own character: some beaches are an easy walk, others take real effort to reach, and conditions shift with the seasons. Serious collectors often visit several beaches across different times of year to improve their chances.
Why Pounamu Is Found Only on the West Coast
The West Coast's geology explains why pounamu doesn't appear anywhere else in New Zealand in the same way. Millions of years ago, nephrite jade formed deep within metamorphic rock beneath what is now the South Island. As the Southern Alps were uplifted and the land shifted over time, these pounamu-bearing rocks rose towards the surface. Today they remain concentrated in the high country above the Hokitika, Grey and Haast river systems. No other part of New Zealand has the same combination of geology, uplift history and river systems needed to expose and carry pounamu down to accessible beaches.
Rainfall and river dynamics do the rest of the work. The West Coast receives some of New Zealand's heaviest rainfall, which drives powerful glacial rivers that constantly erode the mountains and carry material to the coast. The Hokitika River, in particular, acts like nature's conveyor belt, carrying pounamu pieces from high alpine sources down through steep gorges to the sea. On the East Coast, or in the North Island, rivers exist but the underlying rock simply doesn't contain pounamu. This is part of why Ngāi Tahu, the iwi with mana over the West Coast, has long held pounamu as a treasured and defining resource, a status that remains unchanged today.
How to Identify Pounamu on the Beach
Pounamu on a beach rarely looks as polished or vividly green as museum pieces or finished jewellery. Raw stones are usually dulled by a layer of sand or weathering, and they blend in well with ordinary river rocks. The most reliable clue is the surface: even unpolished pounamu has a smooth, slightly waxy feel that differs from quartz or other beach stones. Pick a piece up and it will usually feel noticeably cold and dense, often heavier than an ordinary stone of a similar size. Held up to sunlight, genuine pounamu shows some translucency, especially at thin edges, letting light glow through in a way opaque stones like quartz simply don't.
Colour is another useful clue, though not the one most people expect. Dark green is the classic pounamu colour, but the stone also occurs in pale cream, white, black (kahurangi), grey, and spotted or banded patterns. Many first-time hunters expect uniform dark green and walk straight past pale, highly translucent stones that are just as genuine. The best approach is to compare a few candidate stones side by side along the waterline: weight, surface texture and how light passes through are all more reliable than colour alone.

The Best Times and Practical Tips for Beach Hunting
Timing makes a real difference. After heavy rain, rivers surge with water and material, flushing fresh stone down to the beaches. High tide combined with a rough sea has a similar effect, churning up the shoreline and exposing pounamu that was previously buried. Many collectors plan West Coast trips for the days immediately after a storm. Checking the local weather forecast and tide times before you go is worth the five minutes: low tide exposes more beach to search, but the waterline itself, where pounamu tends to concentrate, is often most active during the tidal shift and right after a disturbance.
A little preparation goes a long way. Sturdy, waterproof footwear with good grip matters, since West Coast beaches are often slippery and uneven, with hidden rocks and sudden drop-offs. A small day pack with water, sun protection and a simple cloth bag for anything you find is enough. Search methodically along the waterline and around river mouths, since these are natural collection points. Don't expect instant results; pounamu hunting rewards patience more than effort, and some visits turn up nothing at all while others produce several finds in an afternoon. That unpredictability is part of the appeal.
Legal and Ethical Considerations for Collectors
Before heading to a West Coast beach, it helps to understand who the stone legally belongs to. Under the Ngāi Tahu (Pounamu Vesting) Act 1997, ownership of naturally occurring pounamu within Ngāi Tahu's traditional boundaries, including the West Coast, sits with Te Rūnanga o Ngāi Tahu. Fossicking, picking up loose stones you can carry unaided from the beach, is recognised as an activity anyone can take part in. Pounamu still embedded in riverbeds and catchments is treated differently: taking it from there is generally reserved for Poutini Ngāi Tahu descendants or those with explicit permission. Large-scale extraction, commercial mining, and selling raw stone without authorisation are all against the law, and exporting significant quantities of raw or partially processed pounamu without permission is unlawful too. Rules and enforcement can change, so checking current guidance from Ngāi Tahu or the Department of Conservation before you go is always the safest approach.
Beyond the legal side sits the deeper cultural one. Pounamu is a taonga, a treasure with spiritual and historical significance to Māori. For Ngāi Tahu, it represents ancestral connection, skill and mana. Collecting it means engaging with something far older and more meaningful than an interesting stone. Many collectors approach the beach with a sense of care rather than treating it as a free-for-all, and that mindset is worth carrying with you, whatever you find.
Whether you're planning a dedicated trip to Hokitika, passing through Greymouth, or exploring the more remote Haast coastline, West Coast pounamu beaches offer a genuine encounter with one of the world's more unusual stones. Knowing where to look, what to look for, and how to collect respectfully is most of the way there. For the fuller cultural picture behind the stone itself, see our guide to what pounamu is.
Frequently Asked Questions About Finding Pounamu on the Beach
Fossicking, picking up loose stones you can carry unaided, is a recognised activity anyone can take part in on West Coast beaches. Pounamu still embedded in riverbeds and catchments is treated differently under the Ngāi Tahu (Pounamu Vesting) Act 1997, and taking it from there is generally reserved for Poutini Ngāi Tahu descendants or those with explicit permission. Rules can change, so it's worth checking current guidance from Ngāi Tahu or the Department of Conservation before you go.
Hokitika is the most accessible and well known pounamu beach, thanks to the Hokitika River constantly washing stone down from the high country. Greymouth and Haast are also reliable, and each has its own access and conditions, so many collectors visit more than one across different seasons.
Raw pounamu rarely looks like polished jewellery. It's usually dulled by sand or weathering and blends in with ordinary river stones. The best clues are a smooth, slightly waxy surface, a cold and dense feel, and some translucency when held up to sunlight. For more detail, see our authenticity guide.
Yes. Loose stone fossicked from the open beach is treated differently from pounamu still sitting in riverbeds or catchments. Taking stone from rivers is generally reserved for Poutini Ngāi Tahu descendants or those with permission, and large-scale extraction or commercial mining without authorisation is against the law.
There's no single best season, but timing around weather matters more than the calendar. The days right after heavy rain or a high tide with rough seas tend to bring fresh stone down from the rivers and expose more of it along the waterline.
Our West Coast region guide lists carvers, galleries and stores based right where the pounamu comes from, a good starting point if you'd prefer a verified piece over a beach find.
