The South African administration continued the so-called " Police Zone " in south , a region created by the Germans covering about two-thirds of the province later to become Namibia . Ovambo people were not allowed to move into the Police Zone , neither other tribes nor Europeans could move north without permits . This isolated the Ovambo people . However , because of labor shortage in the Police Zone and South Africa , in part because of massacre of native Africans such as through the Herero and Namaqua genocide , the South African government allowed migrant wage labor . Numerous Ovambo people became migrant labor , but with segregation and highly restrained human rights , in South African towns such as Cape Town and in the Police Zone
