The New Zealand Society for Oncology is governed by an Executive Committee. This committee consists of a President, Vice President, Secretary/Treasurer and three other members. The committee shall include the immediate past convener of the annual meeting and the convener of the next annual meeting. The committee shall have the power to co-opt such other persons as the executive committee considers appropriate. The office of the President may be held by one person for not more than two consecutive years, but after being out of such office for one year, such a person shall be eligible for re-election as President. The maximum term of office for all members of the executive committee (including President and Vice President) will be two years, except for the convenor of the next annual meeting who will be appointed for one year, and the following year will continue appointment for one more year as the Convenor of the last annual meeting. The common practice of the Society is for the Vice President to automatically become President on the retirement of the current President.
The members of the Executive Committee shall be elected at the Annual General Meeting by nomination and ballot. The Executive Committee shall have power to fill a casual vacancy on the Executive Committee.
The Executive Committee shall annually appoint a Convenor to organise the annual conference and shall have the power to remove the convenor if the convenor is not adequately discharging their responsibilities.
