On June 11, United Future submitted a new application for registration.
Chief electoral officer Robert Peden said the application was declined because it lacked the signed consent by the party's auditor and there was no evidence the party had the required membership.
The party sent in a spreadsheet of members' names and details on June 12, but it was not supported by any signed and dated evidence from its members.
Under the old rule the party needed to provide the commission signed and dated evidence from at least 500 current financial members.
This included the member's name and residential address, confirmation that the person is eligible to enrol as an elector, and amount of membership fee paid, authorisation for the party to record them as a financial member of the party and authorisation for the party to release their membership details to the commission for the purposes of the application to register the party.
