Roaring tractors and blasting horns could be heard on the central streets of Northland towns today as farmers protest the Government’s livestock emissions plan.

The world-first scheme that will see farmers paying for agricultural emissions in some form by 2025 is out for consultation from today.

It marks a significant step in a decades-long process to account for agriculture in climate change policy, which makes up half of the country’s greenhouse gas emissions.

The “We’re Not Going to Take It” national protest by Groundswell NZ has utes, tractors and trucks converging on the country’s main centres.

Almost 60 convoys are planned nationwide – some hit the road as early as 8am to enter the city centres. The Northland leg of the protest had tractors rolling through Whangārei, Dargaville and Kaitāia.

Groundswell organiser Bryce McKenzie described the proposal to price farming emissions as the country’s “nuclear moment” – an echo of Prime Minister Jacinda Ardern’s description of climate change.

McKenzie previously called the emissions pricing plan an “assault on food production and rural communities”.

The local convoys were much smaller than previous protests and less unified, with travellers splitting down different streets.

Around 200 people gathered at Kaitaia’s Te Ahu Centre for the Groundswell protest.

Farmers and supporters headed down along Commerce St in trucks towards the centre of Kaitaia.

A small contingent of the Voices for Freedom joined the protest in Kaitaia, along with FNDC Te Hiku Ward councillors Mate Radich and Felicity Foy, both of whom come from a family of farmers in the area.

While the group was founded by two West Otago farmers, it also has links to the Taxpayers’ Union.

The farming advocacy group attracted criticism after many of its Howl of a Protests rallies carried racist, misogynistic and anti-vax messages on signs and cars last year.

Police were aware of potential protest activity occurring across parts of the country on Thursday, a Police spokesperson said.

Police said they have been in communication with organisers to discuss potential routes and plans and will be monitoring the roading network to respond to any issues as they arise.

Representatives of former National Northland MP Matt King’s newly registered party Democracy NZ were among those taking part in the protest across the country.
