(1) Neither the rule against perpetuities nor any provisions of the Perpetuities Act 1964—
(a) prescribe or restrict the period during which—
(i) the Port Nicholson Block Settlement Trust may exist in law; or
(ii) the trustees, in their capacity as trustees, may hold or deal with property (including income derived from property); or
(b) apply to a settlement document if the application of that rule or the provisions of that Act would otherwise make the document, or a right conferred by the document, invalid or ineffective.
(2) However, if the Port Nicholson Block Settlement Trust is, or becomes, a charitable trust, the application (if any) of the rule against perpetuities or any provision of the Perpetuities Act 1964 to that trust must be determined under the general law.
