Social Security Act 2018, Schedule 3, s 13
Work and Income can choose to calculate your weekly income by either assessing:
how much you were paid over the week, or
how much you earnt over the week (for example, if you’re paid fortnightly).
If you’re getting Accident Compensation Payments (ACC), your benefit will reduce dollar for dollar for the amount of time your ACC payments cover (even if you are paid in a lump sum).
