Marlborough Sounds fishing covers the inshore and inner-bay fisheries of Queen Charlotte Sound, Kenepuru Sound and Pelorus Sound — sheltered, scenic water that supports a varied recreational fishery. Kingfish are the headline summer pelagic species, snapper push down into the outer Sounds in warmer months, and blue cod remain the iconic Sounds species despite long-standing depletion concerns. All marine fishing here is governed by MPI’s Challenger area rules, which include significant restrictions on blue cod (33 cm minimum size, 2 per person per day, seasonal closures).
Practical Information

| Headline summer species | Kingfish (pelagic) |
| Other species | Snapper (outer Sounds, warmer months), blue cod (icon species but restricted), kahawai, flounder, barracouta |
| Blue cod limits | 33 cm minimum, 2/person/day, seasonal closures during spawning |
| Marine fishing rules | MPI Challenger area — check current edition before keeping fish |
| Best season | Late spring through early autumn — water temperature drives species movement |

About Sounds Fishing
The Marlborough Sounds are one of New Zealand’s most-fished inshore marine areas — a network of sheltered drowned river valleys that hold a varied range of species across the warmer half of the year. The three main Sounds — Queen Charlotte, Kenepuru and Pelorus — each have their own character, with the outer reaches more exposed to Cook Strait and the inner bays calmer and more sheltered.
Kingfish are the pelagic summer headline — large fast-moving fish that work surface schools through the outer Sounds and the entrances to the larger bays. Trolling and jigging are the standard approaches. Snapper push down into the outer Sounds in warmer months but are not consistent year-round at this latitude. Blue cod remain the iconic Sounds species, but the fishery has been managed restrictively for many years following documented depletion in the wider Sounds — rocky reef habitat holds blue cod and certain inner bays produce well, while sandy-bottom areas (like much of Port Underwood) are poor habitat. Kahawai, flounder, barracouta and other species round out the fishery across the year.
Regulations
The Sounds are in MPI’s Challenger marine fishing area. The current Challenger rules cover size limits, daily bag limits, accumulation limits and seasonal closures across all recreational species. Blue cod has been the most actively managed species — 33 cm minimum size, 2 per person per day, and seasonal closures during spawning. Always check the current MPI Challenger area rules before keeping fish — restrictions are revised periodically and have tightened in recent years.

Frequently Asked Questions
What can you catch in the Marlborough Sounds?
Kingfish (summer pelagic), snapper (warmer months outer Sounds), blue cod (restricted), kahawai, flounder and barracouta.
What are the blue cod rules?
33 cm minimum size, 2 per person per day, seasonal closures during spawning. Check current MPI Challenger rules.
When is the best season for Sounds fishing?
Late spring through early autumn — warmer water drives species movement.
Where are the main boat ramps?
Picton, Waikawa Bay and Havelock all have public ramps suited to trailer boats.
Where do you fish for blue cod in the Sounds?
Rocky reef habitat areas — much of Port Underwood, for example, is sandy bottom and poor blue cod habitat. Queen Charlotte Sound outer reaches and certain inner reef areas produce best.
