A Lease Variation Instrument cannot be used to renew an expired lease.
Lease Variation Instruments are designed for use only for dealings under section 92 Land Transfer Act 2017.
Pursuant to section 92(3), a Lease Variation Instrument extending the term of a lease must be registered before the expiry of the then current term of the lease.
Consequently, a new Lease Instrument in renewal is required once the term of the existing lease has expired.
