Like many other playwrights in New Zealand, Allen got his first taste for writing on Bill Manhire´s Creative Writing course in 1986. After dabbling in poetry and being too scared too submit any for publication, he got hooked on acting and graduated from Toi Whakaari: New Zealand Drama School in 1991.
Allen then spent a number of years acting in Wellington, appearing in A Doll´s House, A Comedy of Errors, Unidentified Human Remains and the True Nature of Love and Twelfth Night. He also made appearances in the New Zealand television shows Cover Story, Fallout and Mirror Mirror.
He started writing scripts with Stephen Bain after they left Toi Whakaari and they put on The Supermarket of Love and wrote a short film together Taking a Bath which was produced in 1994.
His first solo effort, Weightless was produced by Radio New Zealand in 1995 and his first stage play The Vampyre Dances premiered at Circa in 1996.
In the same year he moved to Australia and began a Graduate Diploma in Writing at Swinburne University in Melbourne. Here he discovered the Internet and since then has created a number of award-winning hypertext fiction pieces and interactives.
After a number of readings in Australia, his first Australian production was Deviations, which was performed in Melbourne and Canberra in 2000.
Allen is currently living in London and works in web development.
