War measures such as the 1916 Amendment to the War Regulations Act and the Revocation of Naturalisation Act and Registration of Aliens Act of 1917 addressed denaturalisation procedures for women. Under the 1916 amendment, wives of enemy aliens were automatically denaturalised as enemy aliens, even if they had been born British. Provisions in the 1917 Revocation of Naturalisation Act stated that revocation of an enemy alien's nationality did not impact his wife and minor children. The Registration Act merely required an alien to list the names and ages of his wife and children. However, an amendment to the Registration of Aliens Act in 1920 clarified that married women in New Zealand who lost their nationality because of marriage were required to register as aliens. Despite the contradictory provisions in the law, women like Soljak were deprived of their nationality during the war. The experience turned her life towards activism, bringing her to national prominence. Political activism (1920–1946) In 1920, the family moved to Auckland and Soljak joined the Auckland Women's Political League, which five years later became the Auckland women's branch of the New Zealand Labour Party. Soljak led a public fight, alongside Elizabeth McCombs, against the nationality laws, speaking to Parliament and publishing articles in the local papers on the unfairness of the legislation. With the break-up of the Austrian Empire, Peter chose to align his nationality with the Kingdom of Serbs, Croats and Slovenes, later Yugoslavia, in 1922. In 1923, New Zealand adopted the British nationality scheme, which clearly specified that New Zealand women who married foreign men automatically lost their nationality upon marriage. Working with allies like Emily Gibson and Peter Fraser, Soljak pressed for legislation for women to have independent nationality. Fraser introduced a bill in 1927, but it was unsuccessful. In 1928, Peter Soljak naturalised, and through his action Soljak regained her British nationality under an amendment passed in 1935, but only while in New Zealand. When travelling abroad, she had to use a passport which was marked "New Zealand born, wife of an alien, now naturalised" and regularly register with the police. From 1926, Soljak worked on women's issues. She fought for women to receive unemployment benefits, as politicians ignored their homelessness and their need to work. In 1931, she worked on the Auckland Unemployed Women's Emergency Committee, but resigned when she realised there were no funds to help women and that their actions
