The winner of the $100 voucher will be drawn at random from all eligible participants on the last day of each month or the next working day. Eligibility depends on up to date survey completion. The winner will be contacted by telephone using the details provided to the MAPP Research team. If a winner cannot be contacted after reasonable attempts by MAPP, the prize will be forfeited and another winner drawn. To maintain confidentiality, winners' name will not be published. The draw results are final and no correspondence will be entered into.
