Jacinda Ardern receives death threat as row over use of poison grows

Use of deadly 1080 bait has led to New Zealand government staff being abused, locked in national parks and harassed online

The New Zealand prime minister has been the subject of a death threat from environmental campaigners who have intensified their opposition to the government's use of the poison 1080 to tackle invasive wildlife.

Jacinda Ardern told a local television station on Tuesday that she had received a number of threats from anti-1080 protesters, including at least one against her life, but said she was more concerned about increasing levels of harassment and violence to conservation staff.
