Our People

Rachel Antony, CEO

Rachel Antony, CEO

Rachel has an extensive background in factual, entertainment and documentary production in New Zealand and internationally.

Rachel Antony, Greenstone’s CEO since 2017, has over 25 years’ experience across development, research and production in Aotearoa New Zealand, Australia and internationally. Inherently nosy, she began her career with a degree in journalism and has worked across dozens of documentary, observational reality and entertainment programmes.

Rachel spent two years juggling producing in Sydney with AFTRS’s Screen Business postgraduate programme and while she’s also had stints in publishing, travel and e-commerce, the screen sector always pulls her back. Greenstone has successfully diversified into more drama production recently, but Rachel’s experiences as a documentary producer mean she’s a firm believer that fact is invariably stranger than fiction.

Passionate about seeing NZ’s creative industries thrive, Rachel is on the boards of Screenrights and innovative NZ theatre company Nightsong, and was a steering committee member for NZ’s Screen Sector Strategy 2030.

Tara Pradhan, Director Government & International Relations, CEO Middle East

Tara is a strategy, partnerships and stakeholder relations leader with a focus on social change.

With a background in the public and NFP sectors, Tara was formerly Head of Vision Partners at World Vision New Zealand and worked as Communications and Stakeholder Manager at the New Zealand Transport Agency. Prior to this, she was with Auckland Council and her experience in local government includes senior roles in international relations; economic development; strategy; creative industries; major events, and film facilitation.

Tara played a key role in establishing Film Auckland and served as a board member for ten years. She is a Leadership New Zealand alumnus and former trustee and is a member of the Be. Accessible Fab50 and a Be. Employed mentor.

Tash Christie, Head of Factual

Tash Christie, Head of Factual

Tash is one of Greenstone’s – and New Zealand’s - most experienced producers

Tash is the Head of Factual and Executive Producer across Greenstone’s diverse documentary and entertainment production slate.

With over 25 years of media and theatre experience under her belt, Tash has pretty much helmed it all – from festival docos, The Women of Pike River and Pictures of Susan, to science-led series, The Good Shit and Peak Antibiotics, Kid’s content and series, Young Riders and K-Pop Academy and primetime favourites, Motorway Patrol, Origins, Artefact, Dog Squad and The Big Ward.

Tash is a committed champion of collaboration. Online documentaries, Under The Bridge and Fighting the Demon, which she produced in tandem with the investigative team at the New Zealand Herald have won journalism awards.

Tash’s superpower is maintaining a sense of humour in even the toughest of circumstances.

Kylie Croft, Head of Production - Operations

Kylie Croft (Ngāti Toa) has been a secret ingredient in Greenstone’s successful (on time, on budget, top-rating) series for over a decade.

Kylie’s role gives her a busy and varied work slate, which can be best summed up by her favourite Māori proverb – ‘He aha te mea nui o tea o (What is the most important thing in the world)?
He tangata, he tangata, he tangata! (it is people, it is people, it is people!)’.

She’s Production Managed and Line Produced a huge variety of GS shows, including The Zoo, The Tem Show, Serious Crash Unit, Decades in Colour, Honey Wars, and Highway Patrol. She now works with all production teams to navigate the often 'twisty-turny' path from prep through to delivery.

Kylie’s passionate about Health, Safety and Wellbeing, though she could do without more covid pivots for a while! Her claim to fame is that she’s short enough (just!) to have auditioned as a hobbit on Lord Of The Rings — a missed opportunity, for sure.

Harriet Crampton, Head of Drama
