Johnson was born in Auckland in 1961.

Johnson has taught creative writing at the University of Auckland, the University of Waikato, Auckland University of Technology and Massey University. She co-founded the Auckland Writers' Festival with Peter Wells, and served as creative director and trustee.

In 2025, it was reported that Johnson’s book, Obligate Carnivore, was disqualified from the 2026 Ockham New Zealand Book Awards because its cover was created using artificial intelligence.

Johnson has published novels, poetry, plays, and collections of short stories.

In 1985, Johnson won the Bruce Mason Playwriting Award.

In the Montana New Zealand Book Awards, The Whistler, was shortlisted for the fiction award in 1999 and Belief was shortlisted in 2001.
