Carlaw Park was named after him.
Carlaw worked as a waterworks engineer, spending forty six years with the Auckland City Council.
Carlaw served as the President of the New Zealand Rugby League between 1914 and 1919. As Ponsonby's representative on the Auckland Rugby League board, Carlaw was chairman of the board between 1918 and 1920. While in this position he started the negotiations that resulted in the league's acquisition of a Chinese market garden that was transformed into Carlaw Park. The opening, on 21 June 1921, was the result of three years of negotiations between the committee led by Carlaw and the Auckland Hospital Board who owned the land.
