Adapting Saltwater Techniques for Freshwater Success

Saltwater sinking stickbaits being used in CSI waters prove successful for Andrew Susani from Australia.

For angler Andrew Susani, experimenting with fishing techniques is half the thrill.

On a recent family trip to New Zealand, he brought along a compact setup—a 1-3kg travel rod, a 2500 Exist reel, and a selection of 6cm sinking stickbaits—hoping to make the most of any lakeside stays.

Despite this not being a fishing-focused trip, Andrew’s approach demonstrated how his saltwater experience back home in Australia could translate beautifully to new freshwater environments.

Back in Queensland, Andrew often targets species like giant trevally, coral trout, and emperor fish with small, slow-sinking stickbaits. With subtle twitches, these can create a realistic darting motion, mimicking live baitfish often more effectively than traditional minnows or spoons.

At Lake Ruataniwha, Andrew found success around the dam’s secluded rock wall, especially in deeper water. In challenging conditions with rising wind, he landed a 9lb salmon. Returning later in calmer conditions, he caught another smaller salmon, solidifying his belief in the stickbait’s freshwater potential.

Andrew’s New Zealand adventure highlighted how innovative saltwater strategies can open new freshwater experiences. With stunning backdrops and plentiful fish, he’s already planning a return trip—this time with an arsenal of small stickbaits to explore more lakes and rivers.

Hydro Canal Fish Release

Over the past week Fish & Game staff have relocated stranded fish from the Tekapo / Takapō spillway to the canals. With the help of Genesis, we moved 31 fish to the Tekapo Canal / Takapō and 32 fish to the Ōhau C Canal.

All were tagged for the purpose of monitoring the growth and movement of fish of Lake Tekapo origin in the Tekapo Canal / Takapō. The tagging project at the Tekapo Canal / Takapō has been in place for over four years – check out this YouTube video to see how we recover and tag the fish before release into the Tekapo Canal / Takapō.

If you catch one of the tagged fish, please report your catch to us – the key piece of information we are after is the four digit tag number, estimated weight, location and date caught. Phone 03 615 8400 or email csi@fishandgame.org.nz if you have any questions or feedback.

If you catch a tagged trout, please report your catch on our online form, here.

The fish released are a bit smaller than your typical target at the canals but would make a good option for new anglers and kids who value just catching a fish above catching big fish.

We have had a report of one angler catching a tagged fish so far from this release.

The Governments New Access Charter

Rangitata Terrace Road Access.

So, what’s it all about?

The Access Charter for Recreational Hunting and Fishing on Public Conservation Land ensures fair, safe, and responsible access for all New Zealanders.

It was developed collaboratively with DOC, stakeholders and other agencies. Minister Todd McClay announced the charter on 2 November 2024.

It guarantees public access to conservation land and waters, supports consistent permitting and licensing procedures, and provides clear information on regulations, safety, and access routes.

The charter emphasises safety, environmental protection, cultural respect, and balancing recreation with conservation goals. Hunters and anglers must follow all rules, including obtaining permits, adhering to catch limits, and respecting other users and the environment.

CSI Fish & Game are committed to maintaining access, maintaining relationships that foster this access for anglers and hunters, and providing up-to-date resources to ensure an enjoyable and sustainable outdoor experience.

A Message From Meridian Energy

Fences and barriers are erected near power stations to keep you safe from emergency discharges like this pictured.

Summer is nearly here and there are a few things to remember when you’re out and about near our canals and hydro assets:

• Remember to park safely, well clear of the roadway and in designated parking areas.
• The rocks on the edge of the canal are super slippery and the canals quickly reach a 10M depth. Please be careful.
• Don’t climb fences around our structures – the fences are there to keep you safe.
• Take it easy when walking down the side of the canals - it’s easy to slip, fall and break something.
• Our hydro station’s water intake and discharge areas have fast flowing aerated water, undercurrents and unpredictable water releases. Please follow the safety information on our safety signs.

Enjoy the canals and hydro assets safely over the summer!

Happy fishing!
