Minister of Conservation Maggie Barry told the parliamentary committee the $11.2m project would focus on growing the kiwi population to a sustainable level through careful monitoring programmes and predator extermination.
DoC-funded kiwi sanctuaries would be set up so kiwis could be released into safe, predator-free environments.
The Greens accused the Government of using Save Our Iconic Kiwi to distract people from a broader agenda of cuts to conservation funding.
"The much-vaunted $11.2 million directed to the grandly titled 'Save Our Iconic Kiwi Initiative' is funded from DoC's natural heritage management programme, which has been cut from $166 million budgeted in 2014/15 to $159 million," Green Party MP Eugenie Sage said after the budget announcement.
"There is no genuine commitment to saving our national symbol when the Government is cutting funding for DoC's wider programme of maintaining, restoring and protecting habitats and species and simply ring fencing some money for kiwi work," she added.
