Campbell's poetry expresses her personal experiences and struggles, and often demonstrates wit and a sense of humor. In
The Oxford Companion to New Zealand Literature,
Roger Robinson suggests that the role of mythology within her poetry speaks about gender roles and sexuality as well as domesticity; he states that Campbell's poetry "can form unexpected links, between the mythic and the domestic, for instance, as in 'Maui', or the universal and psychological, as in 'Things Random' or 'Evolution'." ''
The Cambridge Guide to Women's Writing in English'' and Robinson both describe Campbell's voice as strong. Her work often features a sense of place in the Kāpiti Coast region, where she lived for most of her life. ==Bibliography==
