Kahawai
Kahawai are the second most commonly caught recreational fish in New Zealand, behind only snapper. Native to these waters, they show up from harbours and estuaries to surf beaches and river mouths — almost everywhere inshore.
The Māori name translates roughly as 'strong in the water,' which tells you what to expect when one hits. Accessible to beginners yet genuinely fun on light gear, they're a cornerstone of the NZ inshore fishery.
Scientific Name: Arripis trutta
Also known as Kahawai, kaha
- Torpedo-shaped body, greyish-blue to green-blue on the back, silver flanks, white belly, with a large grey forked tail.
- Black spots scattered across the upper back and shoulders — a key ID mark that separates kahawai from similar-sized trevally or kingfish.
- Juveniles under about 25 cm show yellow spots along the flanks and dark grey stripes on the back rather than the adult spot pattern.
- Common catches run 1–3 kg; fish over 4 kg are solid specimens, and a 10 kg fish from Northland represents a confirmed size record for the species in NZ.
What to know
Habitat Distribution
- Native to New Zealand — found right around the coastline, from Northland to Southland, on both the east and west coasts.
- A second species, the Kermadec Kahawai (Arripis xylabion), lives around the Kermadec Islands and appears seasonally around Northland; it grows considerably larger than the common kahawai.
- Occupy a wide range of inshore environments: open surf beaches, harbour entrances, estuaries, tidal lagoons, and river mouths — wherever baitfish concentrate.
- Prefer cooler, well-oxygenated coastal water; large schools regularly work the surface, making them visible to anglers scanning from shore or a boat.
Key Locations
- Northland — the northern coastline sees the largest kahawai, including seasonal appearances of the bigger Kermadec Kahawai around offshore structure.
- River mouths throughout both islands — tidal lagoons and channels at the mouths of major rivers are reliable year-round holding spots.
- Surf beaches on both coasts — gutters and rips along exposed sandy beaches concentrate fish chasing baitfish pushed in by swell.
- Auckland harbours and the Hauraki Gulf — large schools work the surface regularly, often mixed with kingfish and trevally during summer workups.
Specific Spots
- Tidal lagoons and the channel or gut just inside river mouths funnel baitfish and hold kahawai reliably on the run-in and run-out tide.
- Surf beach gutters and rips concentrate baitfish — kahawai will push right into the wash and occasionally onto the sand itself chasing prey.
- Look for working birds (gannets diving, terns wheeling) over the surface; they mark feeding schools more reliably than any sounder reading.
- In harbours, current edges around headlands, channel drop-offs, and structure like wharves hold fish between surface-feeding bursts.
Kahawai FAQ
Answers from onWater's species guide.
What are the best lures and bait for Kahawai?
Metal slices and knife jigs cast into working schools are the most reliable lure, they sink fast, cast far, and match the slender baitfish kahawai are chasing. Sizes from 20–60 g cover most situations.
What flies work for Kahawai?
Clouser Minnows (which imitate small baitfish) in white/chartreuse or white/blue, sizes 1/0–2/0, are the workhorse fly for kahawai, they sink quickly and have the darting action that triggers strikes from feeding schools.
When is the best time to fish for Kahawai?
Present inshore year-round, but schools are largest and most active from late spring through autumn (October–April) when baitfish and krill are most abundant. Summer (December–February) brings the biggest surface workups, particularly in the Hauraki Gulf and around northern harbours.
How do you catch Kahawai?
Most NZ anglers target kahawai by locating working schools from a boat or elevated shore position, look for diving gannets or surface boils, then cast metal slices or soft-plastics into the melee.
What do Kahawai eat?
Adults feed primarily on baitfish, pilchards, sprats, and anchovies, herding them to the surface in coordinated schools. Match this with metal slices, soft-baits, or streamer flies that imitate small, slender baitfish.
