Brasch became ill with cancer in mid-1972, and before his death was looked after at home by Margaret Scott and another friend
Ruth Dallas. He died in May 1973. His archives are housed at the
Hocken Collections, where over 450 artworks gifted by him can also be seen. In 2013, this collection was included as an entry on the
UNESCO Memory of the World Aotearoa New Zealand Ngā Mahara o te Ao register. Brasch bequeathed his house at
Broad Bay to
Anna Caselberg and her husband
John Caselberg, both New Zealand artists and members of
The Group, and after their deaths in 2004 the house became an artist's retreat. Unlike his earlier work, his final poems dealt more with personal concerns and feelings than with broader issues of national identity. When gifting his journals and personal papers to the Hocken Library, Brasch did so on the condition that they be embargoed for thirty years after his death, to avoid embarrassing his friends. It was illustrated by photographs and by colour reproductions of works from his extensive art collection. In 2007, Margaret Scott edited and wrote the introduction to
Charles Brasch in Egypt, Brasch's account of his time in Egypt. She also began work on transcribing the journals before her own death in 2014, In 2015, the
Otago University Press published a collection of Brasch's
Selected Poems, chosen and edited by his friend and literary executor Alan Roddick. Lawrence Jones in the
Otago Daily Times wrote that the collection "offers the reader in an expertly and sympathetically edited, beautifully designed and printed book of 150 pages the opportunity to experience Brasch's poetic journey": "Such poems, although written in currently unfashionable modes, when they are read in their own terms remain alive and relevant as the testament to the poetic development of a reserved man of great integrity and insight, one of the makers of a New Zealand high culture". ==Personal life==
