After a period of service in World War II, he and his friend Charles Brasch founded the literary magazine Landfall, which Caxton began publishing in 1947.

Glover's later years were marred by alcoholism, forcing him to resign from Caxton Press and subsequent roles, and affecting his personal life.

After a move to Wellington with a new partner, he continued to work as a copywriter, publisher and teacher, and amongst other things served as a member of the New Zealand Literary Fund Advisory Committee from 1955 to 1958 and as president of the Friends of the Turnbull Library from 1963 to 1965.

In addition to writing for the Press, Glover edited New Zealand Motor Owner, the Canterbury University College Review, and Students Association newspaper Canta.

Lowry had by this time set up a press for the Auckland University Students Association and was publishing a magazine called Phoenix.

Caxton published the early works of many New Zealand writers such as Ursula Bethell, R. A. K. Mason, Allen Curnow, Charles Brasch, Frank Sargeson and A. R. D. Fairburn.

He left Christchurch for Auckland, then embarking on the Dominion Monarch for HMS Ganges Shortly Gate, England, arriving in February 1942.

After a short period of training he was assigned to the newly completed destroyer HMS Onslaught for its sea trials.

In June 1944 he took Lord Lovat's 6th commando brigade 2 Troop under Lt-Colonel Mills-Roberts, to Ouistreham, Normandy (near Sword Beach) on D Day earning a Distinguished Service Cross for bravery.

In 1954, Glover worked for Carlton, Carruthers, du Chateau and King as an advertising copywriter and subsequently for Wingfield Press from 1954 to 1962 as production manager and typographer.

Later that year he was awarded an honorary doctorate of literature from Victoria University of Wellington and elected president of honour of the New Zealand Centre of PEN.

The refrain of the latter ("Quardle oodle ardle wardle doodle", imitating the sound of the Australian magpie) is one of the most famous lines in New Zealand poetry.

Playwright Roger Hall wrote a play called Mr Punch about Glover's life.
