This Act may be cited as the Auckland and Suburban Drainage Amendment Act, 1931, and shall be read with and form part of the Auckland and Suburban Drainage Act, 1908 (hereinafter called the principal Act).

Notwithstanding anything contained in the principal Act, it shall be lawful for the Auckland and Suburban Drainage Board (hereinafter called the Board) to undertake and carry out drainage-works, whether in relation to storm-water or sewage, for the benefit of any districts or areas within or adjacent to the Board’s district, and to enter into and enforce agreements with local authorities and other persons or corporations for the payment of the whole or any portion of the cost of any such works.

Every such agreement shall be entered into before the Board begins the works to which the agreement relates, and where any local authority proposes to raise a loan for the purpose of making any payment to the Board in respect of any works such local authority shall not enter into such agreement unless and until it has duly obtained, under the Local Government Loans Board Act, 1926, the consent of the Governor-General in Council to the raising of such loan.

All works heretofore done by the Board and agreements made in connection therewith shall be deemed to have been as lawfully done and entered into as if this Act had then been in force.

The Board may, in addition to the powers conferred on it by section seventy-three of the principal Act in anticipation of receiving moneys payable under any agreement as mentioned in section two hereof, from time to time borrow from any bank by way of overdraft any amount not exceeding the amount payable to it under such agreement.
