Address updates in New Zealand are agency-by-agency. Missing one channel is how tax letters, licence reminders, or visa messages go to an old flat while you wait in a new suburb.
Which systems must know your new address?
Update Inland Revenue in myIR (or form IR238) so tax assessments, Working for Families notices, and refunds reach you: Get an IRD number. Change bank and KiwiSaver postal details the same week. Tell Immigration New Zealand through Immigration Online or the change process that applies to your visa record when contact details matter: Confirm visa status.
Waka Kotahi needs your current address for driver licence and registered vehicle records: Convert your licence and Register a vehicle. If you are a New Zealand citizen or otherwise eligible to enrol, update Vote NZ so parliamentary and local voting papers arrive at the right electorate.
How should you sequence a move between flats?
Keep the tenancy agreement and a utility bill as proof when agencies ask: How to rent a home. Use RealMe where portals require it: Set up RealMe. Update GP and pharmacy records after GP enrolment so prescriptions do not ship to the old street. Make a checklist on moving day rather than trusting one form to cascade everywhere: Paperwork after moving.
Common misconceptions
Assuming council rates or a lease automatically update IRD fails. myIR is separate.
Assuming Immigration learns your new flat from the bank also fails. Update INZ through its own channels when required.
Summary
Treat address change as a multi-agency checklist: IRD, bank, INZ, Waka Kotahi, and Vote NZ when eligible. Matching flat numbers across systems matter more than finishing the list in one afternoon.
