Police investigating threat against Prime Minister Jacinda Ardern delivered to Kerikeri homes

Northland police are continuing to investigate a threat against Prime Minister Jacinda Ardern delivered to letterboxes around Kerikeri.

The handwritten flier was delivered to an unknown number of homes, including in the area around Waipapa Rd, last month.

The message, which managed to spell the Prime Minister's name wrong, started with: ''Very soon a group of us are going to eradicate Jacinda Adern (sic) from this Earth plain for good''.

It went on to claim Ardern was killing people and removing their means to live a fair and happy life.

It was the second such message delivered in the Waipapa Rd area.

Senior Sergeant Phil Le Comte, of Mid North police, said the flier was being examined by the Police Documentation Examination Team in Wellington and the Fingerprint Section in Auckland, as per standard protocols.

Once those inquiries were complete police would reassess what further inquiries were possible in Kerikeri.
