All debentures and Treasury bills issued under this Act shall be enfaced with the name and designation of the Minister or, in the case of money borrowed outside New Zealand, signed by the Loan Agents raising the loan, and shall be countersigned by the Controller and Auditor-General or by any person appointed for that purpose by the Controller and Auditor-General either generally or in a particular case. The fact that any person so countersigns shall be sufficient evidence of his authority to do so, in the absence of proof to the contrary.

It shall be sufficient compliance with the provisions of this section requiring any securities to be signed or countersigned by any person if the required signature is stamped, engraved, lithographed, multigraphed, or otherwise mechanically reproduced on the securities.”
