(1) This Act does not require, or authorise any person to require, a data custodian to share public sector data.
(2) However, a data custodian of public sector data must, within a reasonable period, consider a request for it to share the data, if the request is made:
(a) by an accredited user; and
(b) in the approved form (if any) or in writing (if there is no approved form).
(3) The data custodian may refuse the request for any reason (including that the request is unreasonable), but must give the accredited user written notice of the reasons no later than 28 days after the day the decision to refuse is made.
