People will be automatically enrolled in KiwiSaver under changes being considered by the Government.
All workers would be automatically signed-up to the retirement scheme under the change, unless they asked to opt-out.
National had previously considered such a move, but ruled it out as too expensive.
Finance Minister Bill English said that mass enrolment was now more affordable in the wake of the Government's snap decision to drop the $1000 kickstart, announced as part of Budget 2015.
However, the move would still carry significant cost and it is unclear when it might be implemented, if at all.
