Shortly afterwards, Grant was promoted to second lieutenant and travelled to Cambridge in England for officer training in October 1918. He was wounded in early November, within days of his return to the front. Together with three other New Zealanders who had been awarded the VC, he received his medal from King George V in a ceremony at Buckingham Palace on 27 February 1919. His service with the NZEF ended with his repatriation to New Zealand later that year. His home town of Hāwera gave him a formal welcome on his return on 29 October and he was presented with an inscribed gold watch.
