New Zealand Foreign Affairs Minister Murray McCully says the US-Russia plan is the best hope for a resolution to the wider Syria crisis.
Syria has to submit a comprehensive listing of its chemical weapons stockpiles to the United Nations.
Speaking from San Francisco, Mr McCully told the Q+A programme on TVNZ the plan was welcome and overdue.
Mr McCully said New Zealand hopes the issues can be resolved through the United Nations Security Council.
He said working through the UN should be exhausted before the United States takes unilateral action, but New Zealand understands the US position.
