If an NCA officer is designated as a person having the powers of an immigration officer, the NCA officer has, in relation to any relevant matter, the same powers as an immigration officer would have.

But that is subject to any limitation included in the designation.

In this paragraph “relevant matter”, in relation to a particular power of an immigration officer, means a matter in relation to which that power may be exercised.

This paragraph applies to an enactment if it provides for the issuing of warrants which authorise an immigration officer to exercise any power of an immigration officer.

For the purpose of enabling a designated officer to exercise that power or privilege, the enactment has effect as if the designated officer were an immigration officer.
