of articles for The New Zealand Herald on the topic and attended a Wellington conference in 1934, advocating for birth control. After the conference, she helped found the Sex Hygiene and Birth Regulation Society, renamed the New Zealand Family Planning Association in 1940. In 1935, Soljak led a deputation of members of the Women Workers' Movement to the Prime Minister's office to demand changes to the Women's Unemployment Committees. In the manifesto she presented were demands to disband the committees and terminate the current leadership replacing them with labour bureaux for women, which would be run by women; for government employment placement services for women; for payments to elders, the infirm, and widows; and revised policies concerning separated wives of men who were obtaining relief subsidies. Under the sponsorship of the Women's International League for Peace and Freedom, Soljak attended a Commonwealth women's conference in London (1936–37), where presentations covered such topics as the lack of equal rights for women, peace and social initiatives, trafficking, and women's nationality and immigration rights. She presented a talk to the conference on women's nationality issues in New Zealand. Soljak was finally awarded family maintenance in 1936, but during her trip abroad, Peter attempted to terminate the payments. In 1938, she filed for divorce and was granted a decree nisi, and the divorce was finalised in 1939. Soljak found that she was still classed as a foreign national, despite her New Zealand birth and the termination of her marriage, as the law had no provisions for a woman to recover her nationality lost upon marriage. When the Social Security Act was passed in 1938, she wrote an article in Women Today criticising the fact that though the act entitled single women workers to an unemployment benefit, it paid married women's benefits to their husbands. Soljak joined the New Zealand Rationalist Association in 1940 and in 1941 was elected to serve on the executive committee. The organisation protested the government's treatment of conscientious objectors. That year she continued her campaign against the nationality law, speaking on behalf of the United Women's Movement delegation to the Minister of Internal Affairs. She pointed out that women should have their own nationality and that the current law also impacted the nationality of their children. Soljak continued to campaign throughout the war on behalf of the United Women's Movement, serving as its treasurer in 1944, and the Women's International
