"A London police detective relocates to Rotorua with her husband and children with the notion she is moving to paradise. In the tradition of shows like Twin Peaks and Fargo the series explores the beauty, eeriness and dark underbelly of this small city at the end of the earth.
"Viewers can expect the kind of darkness that characterises Neil's work but with a quirky humour too."
Gareth Neame, executive producer, Carnival Films, said: "We love Neil's take on this story and believe that audiences will be intrigued by the environment and the atmosphere he will create. We're excited to be partnering with the BBC which has had such a successful relationship with Neil and we're also looking forward to embarking on our first project in New Zealand."
Filming is expected to get underway during the second half of 2015. The project will be financed by international licence fees and the Government's New Zealand Screen Production Grant (NZSPG).
It is the first major New Zealand-originated TV production to be announced since the launch of the incentive scheme in April.
"The NZSPG aims to move production companies away from the service model to an intellectual property creation model with long-term benefits realised from a production. This project is a direct example of how that is working in practice.
"It will bring significant investment to the local and national economy. The vast majority of the cast will be New Zealanders and it will employ many people from the New Zealand television and film industry and from the Bay of Plenty region. The initial production is being developed as eight one-hour episodes but our vision is for it to become a long-running series," Mr Fletcher said.
The project offers opportunities for creatives in the New Zealand television industry to work on a world-class project destined for international audiences.
"Libertine was set up with the aim of actively working in the international market. The NZSPG and this series provided us with that opportunity," Mr Fletcher said.
"We are very pleased to be working with producers of the calibre of Carnival and to have the support of the BBC and NBCUniversal. We could not wish for better partners. Their expertise and market strength are a huge asset to the series.
"This will give a team of New Zealand writers the chance to work with some of the world's best in television development and will provide exciting opportunities for New Zealand behind the camera talent."
Mr Cross, who will also be showrunner for the project, is creator and sole writer of the multi-award winning BBC crime thriller Luther, for which he has been twice nominated for an Emmy Award for Outstanding Writing and which screens in more than 160 countries.
His many film and TV projects also include writing the 2013 international hit film Mama, he was lead scriptwriter for the acclaimed Series 6 and Series 7 of BBC spy drama Spooks and recently scripted two episodes of Dr Who.
