Waiau River - photos of Whitebaiting and the river mouth in decades past, c1980s

Whitebaiting, Waiau River and Waiau Mouth. This is what the whitebaiting scene at the Waiau River looked like in 'the season', many years ago now. This series of images, recently donated to the Community Archive, were used to commemorate the new 2024 Whitebaiting season. The new 2025 season starts today on 1 September. We wish all whitebaiters on our river a safe, successful season, and encourage the environmental protection of these taonga, so future generations can also enjoy whitebaiting as we do.

WHITEBAIT:
The Department of Conservation or DOC, summarises what we know as 'Whitebait, as being, "the juveniles of six species of fish, five of which are migratory galaxiids: inanga, banded kōkopu, giant kōkopu, kōaro and shortjaw kōkopu. The sixth species is common smelt." Doc further inform us that the whitebait caught locally from the Waiau River, are predominantly inanga. These are "found in a wide variety of habitats, from tiny creeks, to coastal rivers, lowland streams, lakes and wetlands." Inanga are small and most only survive a year or so, reaching about 100mm in length – the longest one found on record, was 190 mm.

"Because they are poor climbers, inanga are usually found near the coast. Their silvery belly and somewhat forked tail make them easy to distinguish. Found in places as far flung as Chile, Australia and Argentina, inanga are the most widely distributed native freshwater fish in the world," records DOC. They are also Aotearoa New Zealand’s most commonly caught species of whitebait. But as well as this, their population is in decline. Almost all of the Whitebait species are either in decline or threatened, hence new restrictions on catching them. If we want future generations to be able to carry on our tradition of whitebaiting, we need to preserve this previous taonga/treasure.

Whitebaiting is a favourite cherished sport and time-honoured tradition in many parts of the country, and especially at the Waiau River Mouth. Local's have whitebaited here for generations, and can tell tales of times when the beach stretched all the way along Bluecliffs, with road access and parking. In recent times the Waiau Mouth has eroded into the sea, taking a lot of land with it, forever changing the landscape of the river mouth and whitebaiting.

But the landscape at the Waiau Mouth is not the only thing that has now changed. To help protect these taonga or treasured fish species and their habitats for the future, there is now a shorter season and more set rules. For 2024 on the Waiau River in Western Murihiku Southland, the season ran between September 1 & October 30, with whitebaiting only permitted on those days between 5am to 8pm, or 6am to 9pm during daylight savings. The 2025 season is also running from 1 Sept to 30 October.

Now, each person can only have one whitebait net operating at any given time, and this must be attended at all times. The mouth of the net is not allowed to be wider than 4.5 meters. Also, you cannot fish by structures like bridges, culverts, even river junctions. This is to protect these vulnerable fish stocks. If everyone follows the rules, we can all help maintain a healthy river ecosystem, and ensure that whitebait can continue to thrive for the future.

The new regulations which have recently been put into place, are being enforced in a joint effort between Police and DoC. All whitebaiters were notified and encouraged to educate themselves on the new rules and regulations ahead of the 2024 season. It was pleasing to read in a news article from this year, that a patrol of the Waiau River in an effort to ensure adherence to the new regulations, undertaken in late August 2024, there were no reported violations of early whitebaiting. However, there were some later violations of the rules which restricts nighttime whitebaiting.

WAIAU TRUST WHITEBAIT HABITAT:
This project has a focus on the creation of rearing habitats for whitebait, which in turn, helps a diverse range of wildlife which reside or migrate to this coastal environment. According to the Waiau Trust's website (see more in Place Notes), "Adult fish spawn in vegetation at the margins of tidal wetlands and streams, during spring tides in the months of February to April. The fertilised eggs...

Florida International University: Researchers install 3D-printed seawall tiles to support coastal protection and marine life. “The system uses modular, interlocking tiles that can be attached to existing seawalls. Each tile is robotically printed and designed with grooves, ridges, crevices and small pools that create more complex surfaces for marine organisms to attach, shelter and grow.”

Coastal erosion emergency in #Lancelin WA - and locals are left to fundraise $150k for a seawall themselves!
The beach has lost 50m in just 15 months, with a hotel, pub & caravan park now at risk. Nearly $90k raised in 2 weeks by the community, but locals say the state govt is "missing in action".
A $150k state grant for sand renourishment last year washed away within 6 months. Now residents are begging for hard infrastructure before their town slips into the ocean.
WA Nationals leader Shane Love says it's "outrageous" locals have to self-fund. Meanwhile, minister Jessica Stojkovski warns seawalls could affect other coastal areas - but locals point to Perth's miles-long seawall as proof it works.

When does community fundraising become a national disgrace?

Building Natural Seawalls To Fight Off The Rising Tide

https://web.brid.gy/r/https://hackaday.com/2026/01/30/building-natural-seawalls-to-fight-off-the-rising-tide/

Australia’s beaches are not just postcard scenery. They are living ecosystems, natural storm barriers and places of deep cultural and community value. As climate change accelerates sea level rise and extreme weather, coastal erosion is becoming impossible to ignore. This is not a distant future problem. It is happening now, reshaping shorelines and putting homes, wildlife and public access at risk.
The answer is not endless seawalls and short term fixes that push the problem further down the coast. We need smarter planning, protection of dunes and wetlands, and a serious commitment to working with nature rather than against it. Saving our beaches means stronger climate action, better coastal policy and leadership that values long term resilience over quick political wins.

@NormanDunbar There's a bit less to them than there was in the nineties when I lived in Cullen. #CoastalErosion

@junesim63

Difficult decisions are going to have to made and there needs to be more of a national conversation I agree.

At the moment we’re framing it around holiday homes, caravans and in this recent case in #Happisburgh - graves of the dead:

These things are nice to preserve, but not vital. The risk will soon be to whole communities.

Ireland's east coast railway line from Dublin to Wicklow is in trouble. #ClimateChange has accelerated #coastalErosion, requiring protective works which will impede the glorious sea views.

The northern part of the route, from #Dublin to #DunLaoghaire, is one of the oldest in the world. The Dublin and Kingstown Railway opened in 1834, only 4 years after the pioneering Liverpool and Manchester Railway. The line continued to Dalkey in the 1840s, and to Wicklow in 1854. >>
