AT HOP disruption, Metlink service notices and Snapper top-up alerts across Auckland, Wellington and KiwiRail

Millions of journeys a week run on Auckland Transport's AT HOP card, Wellington's Metlink network with Snapper ticketing, and KiwiRail's metro and Great Journeys services. 4notify integrates with AT, Metlink, Snapper and KiwiRail to deliver disruption and balance alerts on each rider's preferred channel.

Line / route preference

Riders save a line (e.g. "Western Line" or "Johnsonville Line") or a station pair; only relevant disruptions are sent.

The 4notify difference

4notify is the only A2P provider that combines Auckland Transport, Metlink, Snapper and KiwiRail into a single envelope with line/station rider preference.

Frequently asked questions
How fast are disruption alerts?

From the AT or Metlink feed to the rider's phone the P50 latency is under 90 seconds; KiwiRail feeds can be slower because of upstream timing.

Can riders get balance alerts without a registered card?

Yes — fleet and organisation accounts subscribe by card range; individual riders subscribe with their own AT HOP or Snapper card number.
