The Companies Office also supports other statutory functions of the various registrars responsible for these registers, and each register was established under separate legislation. So the legislation requires each register to be independently funded from fees charged to the users of the relevant register. This funding model was predicated on each register being operated separately. Over time, the Companies Office has moved towards providing shared services to the registers. A unified approach to the register allowed the Companies Office to establish an organisational structure, an operating model that produces economies of scale in the delivery of registry services and has the ability to leverage technological developments, enabling registry services to be centralised and shared across registers.
