Powers of Attorney Act 2003

An attorney under a power of attorney may, in the exercise of the power—

execute any assurance or instrument with his or her own signature and, where sealing is required, with his or her own seal, or

do any other thing in his or her own name.

An assurance or instrument executed, or thing done, in accordance with subsection (1) is as effectual as if executed or done by the attorney with the signature and seal or, as the case may be, in the name, of the principal.
