New Zealand native tree study strengthens Bioeconomy Science Institute’s forestry leadership
A New Zealand-first native tree study has highlighted the Bioeconomy Science Institute's position as a forestry research leader.
Jonathan Flett says the tree protectors are designed to prevent animals such as rabbits and hares from attacking and damaging young trees.
Seeing plastic tree protectors in the forest prompted a Christchurch cardboard packaging manufacturer to try something different - and now the business is booming.
Pakworld, originally a family-owned business, makes cardboard boxes in which are packed everything from cosmetics to alcohol - and cherries for the horticultural sector.
Jonathan Flett, who was one of the original owners and still works for Pakworld, says seeing the plastic tree protectors occurred at the same time as the Government was rolling out its large tree planting programme. He told Rural News they realised that they could produce a tree protector from cardboard, which was sustainable and naturally biodegradable.
The protectors are designed to prevent animals such as rabbits and hares from attacking and damaging young trees until they are established - be this in a forest or alongside a highway. Flett says they quickly desinged their own cardboard protector and it's been a winner.
"With the plastic protectors, the grower has to go out into the forest and pick up the plastic because it is not biodegradable," he explains. "But with the cardboard product, it will last for between 18 months and two years and will then naturally rot into the soil."
Incorporated into the tree protectors is a small weed mat, which slides around the base of the small newly planted tree and prevents it from being overcome by weeds. The weed mat also has a small hole in it, which allows for a stake to put alongside the tree.
"When we are making the main protector, we use the off-cut from this to make the weed mat so there is little wastage," says Flett.
He admits the idea of the cardboard protector is not new and understands that similar products are manufactured and used in Europe.
On a general note, Flett says they are noticing that discerning customers and consumers are favouring cardboard packaging over plastic. He says people want to do their bit for the environment and using recyclable and biodegradable packaging is one way of doing this.
New Zealand's new Special Agricultural Trade Envoy, Horowhenua dairy farmer, company director and former Minister of Agriculture, Nathan Guy says the Free Trade Agreement (FTA) with India is a good deal for the country.
New figures show dairy farmers are not only holding on to their international workforce, but are also supporting those staff to step into higher-skilled roles on farm.
New tractor deliveries for 2025 jumped 10% compared to the previous year, a reflection of the positive primary sector outlook, according to the Tractor and Machinery Association (TAMA).
Entries have opened for two awards in the New Zealand Dairy Industry Awards (NZDIA) programme, aimed at helping young farmers progress to farm ownership.
Federated Farmers has confirmed interim chief executive Mike Siermans to the role.
Registrations are now open for the 2026 Ruralco Golf Classic, with all proceeds from the event set to support the Mid Canterbury Rural Support Trust.
