Landlord or tenant: who is responsible for the body-protected area?

Usually the practice. The electrical installation inside a tenancy is normally the tenant’s fit-out, and so is keeping it tested: the duty to classify rooms and keep the record sits with the organisation responsible for the premises under AS/NZS 3003, and workplace safety law puts electrical safety on the person in control of the workplace. New Zealand’s RNZCGP guidance puts it the same way: the practice owner, its leadership or the person in control of the premises.

The lease decides the rest. If the landlord supplied the fit-out, or the practice took over rooms that were already body-protected, read the lease for who maintains and tests the electrical installation and who pays for upgrades. Ask the landlord or the previous tenant for the classification record, certificates and the last test results before you sign; if there are none, budget for testing every room and for bringing some up to the standard.

Whatever the lease says, the practice is the one seeing patients in the room, so the practice is the one that needs the test in date.
