1:15 Predator Free NZ:  Is it feasible?

The government has announced it is joining the bold vision for a predator free country by 2050.  It will invest $28m over four years into projects that will remove rats, stoats and possums from around a million hectares of land and will contribute $1 for every $2 invested by councils and private groups.

But how realistic is it, and is the money promised going to be enough?

Our regular economics commentator, Geoff Simmons of the Morgan Foundation crunches the numbers.
