Prime Minister John Key has outlined an overhaul of the welfare system that will require more people to look for work and take jobs when offered.
The new system will scrap the old benefit titles and put beneficiaries into three new categories, depending on their ability to work.
Only those with terminal illness or who are seriously debilitated will not have to undergo work testing.
Mr Key said about 12 per cent of the working age population was on a benefit and that was not sustainable.
All of those currently on the unemployment and sickness benefits will be put on a new 'Jobseeker Support Benefit,' and required to look for full time work. Single parents with children aged over 14 would go on the same benefit.
