Captive bred whio to be released back into wild
The Battle for our Birds continues with the release of more than 30 captive bred whio back into the wild over the next
week.
The whio is the unique native duck only found in New Zealand’s fast flowing waters. Genesis Energy and the Department of
Conservation have partnered together in a five year programme to secure the future of this threatened native bird.
It’s been a record season for whio ducklings bred in captivity with 35 ducklings from three captive sites around New
Zealand. Several captive breeding pairs around the country have had multiple clutches this season.
The whio captive breeding programme involves birds from rivers around the central North Island with breeding sites at
Pukaha Mt Bruce Wildlife Park, Orana Wildlife Park and Peacock Springs in Christchurch.
Whio fledglings, three-month-old ducks, are being released at different sites around the Central North Island over the
next week.
Today six whio were released in the Tongariro area - four onto Tongariro River and two into Whakapapanui Stream – both
locations chosen because of the ongoing predator trapping by local community groups.
Representatives from DOC, Genesis Energy and Tongariro River Rafting were joined by high school students attending the
Kiwi Forever week-long programme, students from Hastings Intermediate and a group from the Blue Duck Project Trust for
the release. Students took an active role in the tagging of the fledglings prior to the release and also the release
onto Tongariro River.
A special ceremony will be held on the banks of the Waiwhakaiho River in Egmont National Park on Thursday to release 16
whio fledglings into the wild.
Once extinct in the Egmont National park, the whio/blue duck is now paddling its way to a population soon to top 100.
These new birds, together with the 25 fledglings from a bumper breeding season within the park, and the 60 adult ducks
already paddling the streams, will boost the Egmont National Park whio population to around 101 ducks.
With fewer than 2500 whio in New Zealand, this Taranaki population is important – particularly as it is the only site in
the country where a whio population has been re-established after the original population became extinct. The last
official sighting of a whio in Egmont National Park prior to recovery attempts was back in 1948.
The remaining two whio to be released are from the WHIONE project where eggs were taken from nests within Egmont
National Park, incubated, hatched and raised in captivity.
Ongoing monitoring and pest control is key to whio survival and population growth within the Egmont National Park. DOC
carries out this work with support from the Central North Island Conservation Charitable Blue Duck Trust and East
Taranaki Environment Trust.
Next week another 11 whio fledglings will be released on Wednesday on Manganui o te Ao River in the Whanganui National
Park. This national security site is a strong example of partnership in action and comes under the banner of the ‘Kia
Wharite’ project. The department, Horizons Regional Council staff, Iwi and landowners continue to work hand in hand to
protect this precious population of birds at this security site.’
March is Whio Forever month which celebrates the “Whio Forever” project, a New Zealand-wide Genesis Energy/DOC
partnership behind a national recovery plan to protect whio/blue duck breeding areas and habitat. The idea is to double
the number of fully secure breeding sites throughout the country and boost pest control to enhance productivity and
survival.

Background Information on whio
• The whio is a threatened species of native duck that is only found in New Zealand’s fast flowing waters.
Featured on New Zealand’s $10 note and with an estimated nationwide population of less than 2500 birds, whio are rarer
than kiwi.
• Whio are adapted to live on fast-flowing rivers so finding whio means you will also find clean, fast-flowing
water with a good supply of underwater insects.
• This makes whio important indicators of ecosystem health – they only exist where there is high quality clean and
healthy waterways.
WHIO FOREVER
• Genesis Energy has a strong historic association with whio through the Tongariro Power Scheme and in 2010 this
association grew through the establishment of Whio Awareness Month (March).
• Today, Genesis Energy and the Department of Conservation (DOC) continue their partnership through The Whio
Forever Programme, which aims to secure the future of whio in the wild and ensure New Zealanders understand and value of
whio in our rivers.
CONSERVATION ISSUE
• The whio are eaten by stoats, ferrets and cats, with the largest impact during nesting time when eggs, young and
females are vulnerable, and also when females are in moult and can’t fly.
• Extensive trapping can manage these predators and work in key whio habitats by DOC and Genesis Energy on the
Whio Forever Project has already seen an increase in whio numbers.
• Whio cannot be moved to predator-free islands like other species because of their reliance on large fast-flowing
rivers.
• Pairs occupy approximately 1km of water – so they need a lot of river to sustain a large population and they
fiercely defend their territories, which makes it difficult to put them with other ducks in captivity.
• They are susceptible to flood events which, destroy nests, fragment broods and wash away their valued food
source.
