Dear gents,
With the text- eradicated by human stupidity. Also one of thousands species.
Peter, words of wisdom.
My name is Pablo, I'm an amateur parakeet breeder from Spain. I have been keeping/breeding kakariki for 4 years now, only red fronted since yellow fronted are fairly difficult to find here. But indeed I would like to keep them as well.
For me it's a fascinating bird, and it makes me sad that NZers don't appreciate what they have at home.
Even sadder for me it's that a country like NZ, of which I thought had enormously high standards in regards of ecology, wildlife conservation, etc... is making naive mistakes.
I'm not sure what need you're trying to satisfy here - the need to restore kakariki to the ecosystem or the need of the backyard breeder to deal with their overabundance of kakariki.
Dave, please don't consider this an attack, but a couple of facts about this.
First of all dealing with overabundance of kakariki is very easy. Open the aviary door and "voilez". Problem solved. That's what most people does when they want to deal with overabundance of a given animal, be it a dog, cat, bird, etc...
Then... I don't know how is the market like in NZ, but I can assure you if Steptoe had some commercial interest of some sort, he could keep 2-3 pairs of kakariki for display and enjoyment, breed them once every 2-3 years to keep a few youngsters and swap for new blood, and use his aviaries to breed commercially interesting species.
So maybe if he makes a proposal to breed other native species is because he is genuinely worried.
Some species might not be critically endangered, but... why wait until it's too late. I think then this is the perfect moment to start a captive-breeding program of some species.
And on the other side I think it's a pity aviculturists can't enjoy their own local species.
About reintroduction of kakariki, Peter probably has a point about adapting a flock of birds before actually releasing them. Very good idea about opening the door, at least we should try.
Placing seed-fruit feeders strategically will help also, so the transition is smoother.
Gecko, nice point on conservation and pest control.
I can't help say if a release of captive bred stock would work in the mainland or not, because all I saw of NZ are pictures.
Maybe I can release a flock of 20 in my neighborhood in Spain and watch their progress.
(now this was a
JOKE)

On the other side I disagree with Steps about bringing any stock from Europe unless the origin is properly researched, and you'll find little help on this.
It's an inexpensive bird and it's bred plentifully. Who cares?
If it were hyacinth macaws or black cockatoos, then I'd say go ahead and research. Kakariki is stupid.
Even people at LoroParque has not much interest in informing etc...
I have invited them several times to drop by
www.kakariki.net and share their opinions/views or simply write an article if possible, etc...
Nothing.
And red fronts are CITES I, and even in Europe the situation is very tight due to people breeding hybrids carelessly.
If an institution like LoroParque got hands on with this a little bit a lot of Euro breeders would improve their practices, etc...
And well... enough of criticism

Dave, even if we might have a different point of view on kakariki, nevetheless my sincerest congratulations for opening up a forum like this and trying to inform people and get involved with conservation and management of native wildlife.
Kind regards,
Pablo
