The Electoral Commission has changed its rules meaning United Future will not have to provide original signed application forms to prove it has more than 500 members.
The commission decided it will now accept signed and dated forms submitted to the party electronically.
The party is in the process of collecting those forms and sending them to the commission.
United Future asked the commission to change its policy to accept evidence of membership based on an electronic spreadsheet of membership data, rather than membership applications signed by each member.
The commission cancelled the registration of United Future as a political party on May 31 after it notified the commission it did not have at least 500 current financial members who were eligible to enrol as voters.
