It has been necessary to withhold certain information in accordance with the following provisions of the Official Information Act 1982. Where information is withheld, the relevant sections of the Act are indicated in the body of the document. Information is withheld where making it available would be likely to prejudice:

  • the security or defence of New Zealand or the international relations of the Government of New Zealand [section 6(a)]

  • the entrusting of information to the Government of New Zealand on a basis of confidence by the Government of any other country or any agency of such a Government [section 6(b)(i)]

Information is also withheld in order to:

  • protect information that would be likely to unreasonably prejudice the commercial position of the person who supplied or is the subject of the information [section 9(2)(b)(ii)]
  • maintain the effective conduct of public affairs through the free and frank expression of opinions [section 9(2)(g)(i)]
  • maintain the confidentiality of advice tendered by Ministers of the Crown and officials [section 9(2)(f)(iv)], and
  • enable a Minister of the Crown or any department to carry on, without prejudice or disadvantage, negotiations [section 9(2)(j)].

Where information is withheld under section 9(2) of the Act it is not considered that the public interest outweighs the need to protect it.


As per usual process, Cabinet was provided with estimated costs and delivery time frames that were subsequently superseded. During the early stages of this procurement process, Cabinet was also provided with the option for an interim capability solution. This interim solution was not pursued.
