Just in Vote Conservation, the committee was also interested in Predator Free New Zealand—the big expansion in that programme in South Westland in the Whataroa area. The director-general highlighted the gains that have been made in predator control, both there and in areas like kōkako in Pureora, where this sustained investment that Government is making in predator control over several years is showing significant improvements in the status of a lot of our threatened species. Going back right to the 1990s, for example, where we only had 830 breeding pairs of kōkako throughout the North Island, now there are some 2,000 breeding pairs. The committee was also interested in a lot of predators like feral cats—the seriousness of the problem of feral cats, both in terms of their direct predation and the impacts of toxoplasmosis. We also heard about the work the department was doing to reduce its climate emissions: a 40 percent reduction in air travel in the last financial year, and a ban on the purchase of internal combustion engines.
