New Zealand Legislation: Acts
Acts are laws made by Parliament
(1) A married couple may enter into a civil union with each other; and 2 people in a civil union with each other, and who are otherwise eligible to marry, may marry each other.
(2) Before changing the form of their relationship under this section, the party who gives the notice required by section 11 of this Act or section 23 of the Marriage Act 1955 must state on the form that the parties are already in a civil union with each other or are married to each other (as the case requires) and that they wish to change the form of their relationship.
(3) The solemnisation of the marriage of 2 people who are in a civil union with each other changes the relationship from a civil union into a marriage; but in any situation in which the duration of the resulting marriage is in issue, the duration of the earlier civil union is to be treated as part of the duration of the marriage.
(4) The solemnisation of a civil union between 2 people who are married to each other changes the relationship from a marriage into a civil union; but in any situation in which the duration of the resulting civil union is in issue, the duration of the earlier marriage is to be treated as part of the duration of the civil union.
