The cat's out of the bag for one of National's most important policies, after some details were mistakenly made public a day before its planned release.
A blunder by a National Party staffer saw details of its welfare reform policy emailed to Sky News on Monday.
The policy, to be launched on Tuesday, is reported to involve getting 46,000 beneficiaries off welfare and into some form of work, including getting 11,000 into part-time work, within the next four years.
The cost will be about $130 million to pay for training but the Government expects to save about $1 billion over four years in reduced welfare payments.
The policy comes as a response to the Government's Welfare Working Group, which made sweeping and controversial recommendations to cut beneficiary numbers.
Those included so-called fit notes for sickness beneficiaries, to say what work they can do, rather than what they can't, sending parents on the domestic purposes benefit back to work when their youngest child reaches one year of age, and requiring unemployment benefit recipients to find paid or volunteer work after six months for their payments to continue.
National has previously announced it will introduce payment cards for 16 and 17-year-olds on the independent youth benefit, to buy food and necessities, while their rent and bills will be paid directly by the state.
Prime Minister John Key will unveil the full policy in Hamilton on Tuesday, with further details still to be confirmed.
