Colin Craig gave a generous Christmas donation to the Conservative Party, despite stepping down as its leader.
The party declared a $22,000 donation from Mr Craig on December 22, on top of earlier donations of $3000, $6000 and $8300 last year.
Political parties must declare individual or separate donations which amount to more than $30,000 within a 12-month period.
The latest donations come despite Mr Craig taking a back seat in the party's operations. He stepped down as leader in June after admitting to inappropriate conduct with a former staff member.
