Wild kiwifruit

KVH works collaboratively with regional councils and landowners to manage wild kiwifruit populations and unmanaged orchards to reduce biosecurity risk to the New Zealand kiwifruit industry.

Wild kiwifruit

In October 2020, KVH and the Bay of Plenty Regional Council (BOPRC) signed an agreement to continue to work together to manage this pest plant over the next 10 years. Under the new agreement, KVH will manage the administration involved in the running of the programme while also contributing $150,000 annually towards control costs and surveillance costs. BOPRC will contribute $100,000 per annum and support KVH in gathering landowner contributions.

KVH has also partnered with Zespri and the Kiwifruit Breeding Centre. Through their significant contributions, the programme has been able to expand and control wild kiwifruit infestations previously left unchecked.

If you know the location of any unrecorded wild kiwifruit infestations, contact your local regional council or unitary authority with details so the infestation can be assessed and programmed for control.

Why control the wild population? The reason wild kiwifruit vines are a biosecurity risk to New Zealand’s kiwifruit industry is that they act as a vector for Psa and other kiwifruit pests and diseases. The wild population can act as a reservoir for biosecurity threats, undermining eradication, and control efforts on commercially productive vines.

They are also a threat to our environment. Wild kiwifruit vines are vigorous climbers, and if left uncontrolled, it can form dense heavy blankets of vines that strangle trees, causing them to die or collapse. Vines can also smother forestry plantations and New Zealand’s native bush.


How to prevent wild kiwifruit establishing

GROWERS

Remove unpicked fruit from vines and mulch as soon as possible. This prevents mass feeding by birds and allows the fruit to compost as quickly as possible.

POST-HARVEST OPERATORS

Cover bins of reject fruit to prevent birds feeding on ripening fruit.

FARMERS

Cover stockpiles of fruit with shade cloth, windbreak netting or something similar to prevent birds from getting to any fruit. Feed out only what will be eaten by stock at one time to prevent birds from eating leftovers.

MEMBERS OF THE PUBLIC

Be very careful with the disposal of kiwifruit, particularly while out in the bush.

KILL WILD KIWIFRUIT PLANTS

Cut vines at ground level. Apply Vigilant Gel® herbicide to the top and sides of the cut stump or any exposed roots. Ring-bark stumps or large roots with a machete or pruning saw to assist absorption of the herbicide gel. Carefully trace all vine stems to find where they may have taken root. Cut any rooted stems at ground level and apply Vigilant Gel®. Never apply Vigilant Gel to stumps within a kiwifruit orchard. For controlling kiwifruit stumps within an orchard, please refer here.

Meet the team

In the last issue of the Bulletin, we started our meet the team series, sharing more about the roles we have, and how each of us interact with you, our readers and growers, in our day-to-day activities. This week, we introduce Anna Li. I’m Anna and I joined KVH in August 2024 as the Systems Coordinator. My role is to support KVH’s IT infrastructure and security and provide data and mapping support to the team. I also create practical new tools and systems for KVH that we can use for online services to growers, particularly around traceability. My background spans web development, software programming, and mapping. I have a horticulture certificate too, which gives me deep insights into pest and disease control within orchard management. Before joining KVH, I was a professional landscape architect – something I’m still really interested in. I worked on residential projects and large public spaces, and gained valuable experience in mapping, which I use to this day. I’m excited to be part of KVH and look forward to working with you all to support our growers.

Cruise season is upon us

The 2024/25 cruise season in New Zealand is officially underway, with 45 cruise ships set to make a total of 957 stops around the country. Four cruise lines that haven’t been here since pre-Covid times are also coming back. We often get questions from growers about Biosecurity New Zealand’s Recognised Cruise Line Programme (RCLP), which checks how cruise lines handle risks. Here’s a rundown of what’s covered in the programme: Refuse management – such as using steam to sterilise bottles and containers that have been used for food.Pest and provision management – ensuring things like live plants are treated, pest traps are checked, and there’s a solid plan for managing pests in provisions.Passenger management – for example, limiting the serving of whole fruit and honey, and making sure passengers get biosecurity information at least two days before arriving.Biosecurity awareness – this includes making sure crew members are well trained. Starting this season, operators with a good track record of compliance may be able to keep their approval status for up to three years for both topside and underwater biosecurity. Evaluations will still happen every year, and operators will need to meet strict standards to maintain their approval. Also, Biosecurity New Zealand is changing how they do audits - officers will now carry out checks throughout the entire cruise season, not just at the first port of arrival. In the Bay of Plenty, we also have the Port of Tauranga Biosecurity Excellence programme, which involves the Port, KVH, Biosecurity New Zealand, and other local industry and council working together to raise awareness with frontline staff and ensure there are no biosecurity incursions through the Port.
