Where to Look for Ambergris on New Zealand's Coast

New Zealand sits in some of the world's richest sperm whale waters. Here's where - and when - ambergris is most likely to wash ashore.

Geography & Ocean Currents

Why New Zealand Produces Ambergris Finds

Sperm whales (the sole biological source of ambergris) are frequent visitors to New Zealand's deep offshore waters, particularly around the Kaikōura Canyon - one of the world's most productive whale habitats. Prevailing westerly and southerly swells carry oceanic material toward New Zealand's long, exposed coastlines, making them natural collection points for deep-sea byproducts including ambergris.

New Zealand's low population density and vast stretches of undeveloped coastline mean many finds go unnoticed. That's an opportunity.

Key regions in New Zealand for ambergris finds

Key Regions for NZ Finders

These regions have historically produced ambergris finds — but any NZ beach is worth checking after a storm.

Northland & Ninety Mile Beach

Historically Productive

Long, remote stretches of west-facing beach exposed to Tasman Sea swells. Low foot traffic. Historically productive for ocean debris including ambergris. Sarah M., one of our active NZ suppliers, made her first find near Dargaville — right in this region.

Coromandel Peninsula

Verified Finds

Verified finds have been recorded along this coastline. Rocky bays and pocket beaches trap material arriving from the north and east.

Bay of Plenty

Post-Storm Priority

Broad, sweeping beaches with consistent swell. Worth checking after significant storm events when oceanic material deposits along the shoreline.

West Coast (Westland)

High Reward

Some of the most remote and least-walked coastline in New Zealand. High-energy surf regularly deposits deep-sea material. Challenging to access but rewarding.

Southland & Stewart Island / Rakiura

Southern Ocean Exposure

The southernmost coastline in New Zealand. Exposed to Southern Ocean swells and close to Antarctic current paths. Finds have been reported in this region.

Ambergris can wash up anywhere on any New Zealand beach. These are historically productive regions — not guarantees. Always check any unusual waxy or resinous material regardless of location.

Best Times to Search

Seasonality and storm activity are the two biggest predictors of productive beach conditions.

Summer

Good

December – March

Calmer conditions make walking and searching easier. Good for systematic coverage of longer beaches like Ninety Mile Beach.

Post-Storm

Best

Any season

The best time. Storm swells dislodge and deposit oceanic material that has been floating offshore. Check beaches within 24–48 hours after a significant storm.

Autumn

Very Good

March – May

Transitional swells from the south and west increase deposit frequency on western coastlines. A productive transition period.

Winter

High Swell

June – August

Rough conditions but high swell activity. Western and southern beaches most productive if accessible. Not for the fainthearted.

What to Look For

Focus on the high tide line — the band of debris deposited at the furthest reach of the last tide. Ambergris sits here alongside kelp, driftwood, and other oceanic material.

Look for anything waxy, matte-finished, and lighter than it appears. Ambergris is often mistaken for a smoothed rock until you pick it up.

After a storm, move quickly. Popular beaches are covered by other walkers within hours.

Career Opportunity

Turn This Into a Regular Income.

Some of our New Zealand suppliers walk their local beach twice a week. It doesn't take long before you develop an eye for what doesn't belong there.
