You apply once and sign once. After that, everything the school needs from you arrives as a link in your email. The placement request, the check-in, the pay statement. Nothing to install, no password to remember, and it works on the phone in your kitchen.
Pay is worked out night by night from the dates the school holds. If your student is away for a weekend, or has a dietary need the school pays extra for, it is on the statement as its own line, and you see the statement before the money arrives.

Any check-in lets you raise a concern. It opens a case at the school and the homestay manager is told straight away. For anything urgent, use your school's after-hours number.
Your police vetting, home visit notes and bank details are held by your school in Harbor, in a database in Australia, under the NZ Privacy Act 2020. Agents and other families never see them.
Hosting is arranged by the school, not by Harbor. Ask your local school's international office. If they use Harbor, they will send you the application link.
