Uther completed a BA (Hons) in Theatre at Victoria University in 2010. In 2009, he co-founded My Accomplice, an award-winning, audience favourite theatre company with Hannah Banks and Paul Waggott. They created A Play About Space, which saw Uther nominated for Best Newcomer Playwright at the Chapman Tripp Theatre Awards and won Best Theatre at the Dunedin Fringe in 2013, and Everything is Surrounded by Water, a monologue co-written and performed by Uther that won Best Solo at the New Zealand Fringe in 2014 and was nominated for Best New New Zealand Play at the Chapman Tripp Theatre Awards that year.
My Accomplice opened the newly renovated BATS Theatre, Wellington with their STAB commission Watch, which Uther wrote and co-directed. Watch went on to win three Chapman Tripp awards and was nominated for Best Production. In 2015 My Accomplice presented a sequence of 24 radio dramas with Radio New Zealand for the 2015 New Zealand Fringe (one for every day of the festival).
Uther is the creator and “show-runner” of the popular anthology audio-drama podcast The Witching Hours (thewitchinghours.com). His writing has been published in Sport, The Listener, The Wireless, Fishhead, The Pantograph Punch and The Lumiere Reader.
