In registering a plan of subdivision, the registrar of titles must record in the appropriate register—
(a) if the boundaries of land affected by the plan of subdivision are changed on the coming into effect of the plan—any new description as identified on the reverse of the plan; and
(b) if all or part of land affected by the plan of subdivision becomes a reserve on the coming into effect of the plan—the particulars of the reserve; and
(c) if all or part of land affected by the plan of subdivision becomes public use land other than a reserve or road—the particulars of the unallocated State land.
