The surname Losack was first found in Cheshire at Allostock, a township, in the parish of Great Budworth, union and hundred of Northwich. "In the reign of Edward I. the manor [of Allostock] was conveyed by John de Lostock to the Grosvenors, who had their chief residence here."  And over in Anderton, again in Cheshire another branch of the family held a family seat since ancient times. " The manor [of Anderton] was held at an early period by the family of Lostock, from whom Urian de St. Pierre, who died seised of it in 1286, had obtained it by gift."

Emigration to New Zealand followed in the footsteps of the European explorers, such as Captain Cook (1769-70): first came sealers, whalers, missionaries, and traders. By 1838, the British New Zealand Company had begun buying land from the Maori tribes, and selling it to settlers, and, after the Treaty of Waitangi in 1840, many British families set out on the arduous six month journey from Britain to Aotearoa to start a new life. Early immigrants include:
