Most new employees aged 18 to 65 are automatically enrolled when they start a new job with any employer other than an exempt employer.
Those employed for four weeks or less are excluded from automatic enrolment. Some other exceptions also apply.
Most other employees under age 65 can opt in, including some employees working overseas and employees of an ‘exempt employer'.
Detailed Information on KiwiSaver membership is provided by Inland Revenue (leaflet KS3).
Employees can opt out during weeks three to eight (inclusive) of employment via their employer or Inland Revenue. In some situations a late opt-out period may be available.
Membership is allowed of only one KiwiSaver scheme at a time. If an employee is already a member of a KiwiSaver scheme and joins another, the balance from the previous scheme must be transferred to the new scheme.
