The best trace is not simply the strongest one on the shelf. It is the one that suits your target species, fishing method, ground and tackle. A light snapper softbait setup and a kingfish jigging outfit ask very different things of the line between braid and hook.
This guide gives practical starting points for New Zealand saltwater fishing, not universal rules. Adjust them for structure, fish size, lure action and your ability to tie and test the connection. Browse the Braid, leader and terminal tackle collection for leader, braid and replacement rig components.
Trace versus leader: what is the difference?
Anglers often use the words interchangeably. Here, leader means the section joining your mainline to your lure or terminal rig; trace also includes the hook-carrying section of a bait rig. On a ledger setup, the braid-to-leader connection and the branch carrying each hook are separate things. Check both.
Snapper: start with the method
Softbaits over sand and mixed ground
A useful starting point is 15–25 lb leader around 2–3 metres long. Twenty-pound fluorocarbon is a sensible first option, with 25–30 lb worth considering when fishing closer to rough ground. These are tackle-selection suggestions, not a promise that any particular leader will survive contact with reef.
Keep enough length for abrasion protection and a few reties, but test how the connection passes through your guides. If your knot catches, shorten the casting drop or improve the join rather than accepting repeated impacts.
Slow jigs and inchiku-style fishing
Start around 20–30 lb and 2–2.5 metres, then adjust for terrain and the lure's movement. Check the leader near the lure after fish and snags. Replacement assists should suit the jig's shape and attachment system, not just its weight. Explore OK-Pro jig assist hooks and check the complete hook-and-cord length against your jig before rigging.
Bait fishing and rougher ground
For bait fishing, 30–60 lb trace is a useful working range to consider, especially where abrasion is more demanding. Going thicker can protect against wear, but it can also make a small bait or rig less supple. Choose the lightest practical setup that still gives you control and abrasion allowance for your spot.
Flash-as flasher rigs and the pack of ten flasher rigs are ready-rig options to browse. Check the selected rig's hook size, trace rating and local hook rules before use; this guide does not assume those specifications.
Kingfish: structure and technique change the answer
For mechanical jigging, 60–100 lb leader around 2–3 metres long is a practical starting range. Big fish, heavy drag and unforgiving structure may call for heavier material and a suitably matched outfit. A heavier leader does not make a light rod, reel or connection capable of unlimited pressure.
For livebaiting, both nylon mono and fluorocarbon have a place. Nylon is generally more supple, easier to knot and less expensive; fluorocarbon is worth considering when visibility and abrasion are priorities. Match diameter, stiffness and length to bait size and the ground rather than copying another angler's rig without its context.
For topwater lures, check the lure maker's rigging guidance. An overly stiff or heavy leader, oversized terminal hardware or a hook change can alter the way the lure swims. Test the complete rig beside the boat before casting.
Kahawai and blue cod: do not default to kingfish tackle
For kahawai on small lures over open ground, think presentation first. As a practical starting choice, try a 20 lb leader around 1.5–2 metres, then reassess for lure size, wear and bycatch. There is no need to copy a heavy kingfish trace just because both species might be nearby.
For blue cod and mixed bottom fishing, select trace for bottom contact, rig design and the other species you may encounter. Inspect the hook branches as well as the main trace. A multi-hook flasher rig is not automatically appropriate everywhere: check the current rules for your exact area before choosing it.
Fluorocarbon versus monofilament
Fluorocarbon is commonly chosen for lower underwater visibility and abrasion-focused applications. It is not invisible or cut-proof. Stiffness and knot handling vary between products and diameters. Fluoro Salt Leader is the collection's fluorocarbon option; check the available strength before matching it to your outfit.
Nylon monofilament is a practical option when suppleness, ease of knotting and cost matter. Do not assume that every fluorocarbon beats every nylon in abrasion resistance: diameter, formulation, knot quality and actual wear all count. Neither material removes the need to check and replace damaged line.
Connecting braid to leader
An FG knot is a useful connection to learn, especially when the join needs to travel through the rod guides. It is slim, but only reliable when tied, tightened and finished correctly. Practise with your actual braid and leader at home, then pull-test the connection before fishing.
A double uni can be a simpler option on lighter line, but the join is bulkier. Check guide clearance rather than assuming a knot that holds in your hands will cast smoothly. Heavy jigging outfits may also use a PR connection, which requires the right technique and equipment.
If you are changing mainline, browse the multi-coloured 8-strand braid. Select its rating to suit your rod and reel, then test the complete braid-to-leader system. Never wrap braid around your hand to pull-test or free a snag.
Single versus treble hooks: choose for the lure and release plan
New Zealand anglers have different preferences, and forum experience is not a universal rule. Inline singles are worth considering when easier unhooking and release are priorities. Trebles can be part of a lure's intended balance, so a change to singles is not automatically an improvement to its action.
Match hook weight, gape, eye orientation and clearance to the lure; hook size numbers alone are not enough. Test its swimming action after any change. Jig assist hooks are a different arrangement from inline lure singles and should not be treated as interchangeable replacements.
On an appropriate jig setup, a solid ring can carry the leader and assist, with a split ring connecting the jig. Avoid tying leader across a split ring's opening. Ensure assists cannot foul the leader or lock together, and check that every component suits the intended load.
A quick check before the next drop
- Run your fingers carefully along the leader and replace sections with nicks, roughness or flattening.
- Check the join and terminal knot after a snag, hard fight or repeated casting impacts.
- Replace frayed assist cord, damaged hooks and distorted rings.
- Reassess leader length after reties. A once-long leader can become too short to do its job.
- Use a net or suitable landing method. Do not assume leader breaking strain makes it safe to lift a fish or grab a loaded trace.
Check the rules for where you fish
Leader suggestions are not fishing regulations. Before heading out, check Fisheries New Zealand's official area guidance for species limits, sizes, closures and any applicable hook or method restrictions. Use the Auckland/Kermadec rules or Challenger rules where relevant, and select your own area's guidance if fishing elsewhere. Blue cod requirements in particular need a location-specific check.
Build a setup for your fishing
Choose the species and method first, then select material, strength, length and connections as one system. Carry spare leader, retie when damaged and change one variable at a time if presentation or casting suffers. Explore Braid, leader and terminal tackle to put together your next setup.
