OBS_VALUE: There are no limitations on law firms beyond those required for all foreign companies by the New Zealand Companies Act 1993. The Companies Act sets out the main requirements for companies domiciled overseas to operate in New Zealand. This can be achieved by: - Incorporation of a new subsidiary company; or  - Registering the foreign company as a branch in New Zealand; or  - Acquiring shares in a pre-existing New Zealand company or entering a joint venture with a New Zealand company. In all instances, registration with the Companies Office is required.
