Sonya is a former TV reporter who became a writer, charity founder, and author. After more than 20 years in broadcast journalism — reporting and presenting for programmes such as One News, Breakfast, 20/20, and Sunday — she completed a Master of Creative Writing at the University of Auckland. There she wrote Spark Hunter, an adventure-fantasy novel for readers aged ten and up, set in Fiordland National Park. The book became a bestseller and won the NZSA Best First Book Award at the 2022 NZ Book Awards for Children and Young Adults, as well as a Storylines Notable Book Award. Its sequel, The Secret Green, was published in July 2025 by Allen & Unwin.

She also writes creative non-fiction, essays, and reviews, and regularly gives talks, workshops, and chairs sessions at writers’ festivals — blending her love of journalism and literature. Passionate about the power of books to build empathy and wonder, she founded Kiwi Christmas Books, a charity that gifts brand new books to children who might otherwise go without. Originally from the Deep South, she now lives in Auckland with her husband Pete, their two sons, a cat named Graham and a dog named Dusky.
