The Mau remained true to this sentiment, and despite the exile of Nelson, continued to use civil disobedience to oppose the New Zealand administration. They boycotted imported products, refused to pay taxes and formed their own "police force", picketing stores in Apia to prevent the payment of customs to the authorities. Village committees established by the administration ceased to meet and government officials were ignored when they went on tour. Births and deaths went unregistered. Coconuts went unharvested, and the banana plantations were neglected.
