[2] After completing his education, Curnow worked from 1929 to 1930 at the Christchurch Sun, before moving once again to Auckland to prepare for the Anglican ministry at St John's Theological College (1931–1933).

In 1934 Curnow returned to the South Island, where he started a correspondence with Iris Wilkinson and Alan Mulgan, as well as finding a job at The Press, the Christchurch morning daily newspaper, having decided against a career in the Anglican ministry.

He then taught English at Auckland University from 1950 to 1976, during which he spent much time at his holiday home on Lone Kauri Road in the central Waitākere Ranges.

[7] Curnow wrote a long-running weekly satirical poetry column under the pen-name of Whim Wham for The Press from 1937, and then The New Zealand Herald from 1951, finishing in 1988 – a far-reaching period in which he turned his keen wit to many world issues,[8] from Franco, Hitler, Vietnam, Apartheid, and the White Australia policy, to the internal politics of Walter Nash and the eras of Robert Muldoon and David Lange, all interspersed with humorous commentary on New Zealand's obsession with rugby and other light-hearted subjects.

His landscape/isolation centred poetry reflects varying degrees of engaged fear, guilt, accusation, rage and possessiveness, creating an important but, both previously and still, much neglected dialogue with the New Zealand landscape.
