At LINZ we manage around 2 million hectares of Crown lands and waterways across New Zealand including many of our treasured lakes, rivers and high country.
Our biosecurity operations specialise in aquatic and land-based pest and weed management, as well as monitoring and surveillance.
Our team provides advice to cross-agency projects including the New Zealand Wilding Conifer Control Programme and the Clean Check Dry programme which aims to prevent the spread of water weeds by swimmers and boaties.
New funding: bad news for pests and weeds
In mid-2020 the LINZ biosecurity programme was allocated $40m over four years from the Government’s $1.3 billion Jobs for Nature Covid-19 recovery package.
This additional funding, along with significant budget increases over the past two years means LINZ now has around $17.25 million per year (up from around $4.5 million in 2018/19), totalling nearly $70 million over the next four years.
This massive boost to our biosecurity programme will deliver 70-90 new jobs.
Work will be carried out by a range of new and existing contractors, iwi and community partners, in conjunction with our well-established biosecurity control programme.
Unlike other agencies under the Jobs for Nature programme LINZ funding is not available for contestable allocation.
Where we work – our beautiful back yard
In the South Island our biosecurity work focuses on LINZ managed areas of the Otago region, the Canterbury high country, including Te Manahuna – The Mackenzie Basin, and some of New Zealand’s most beautiful lakes and braided rivers including Lake Wanaka and the Rakaia River.
In the North Island priority areas include the Waikato River and Te Arawa Lakes where weed infestations impact the cultural and recreational value of these places.
Maps and data keep tabs on pests and weeds
As New Zealand’s official mapping agency we develop maps and geospatial tools to help identify and track pests and weeds across the country.
This information helps us make good decisions to support the restoration of our birds, plants and fish to their natural habitats.
Like Covid-19, pests and weeds don’t recognise personal or property boundaries.
Seeds blow about and travel downstream, and weeds get stuck in motors and move about with their owners from lake to lake.
To get the best results and use our funds efficiently we want to work across river and lake systems so that our on-the-ground biosecurity control operations are well co-ordinated and produce the best results with the least interruption.
This means working closely with community groups, local and regional councils, neighbouring landowners, industry, business, environmental research and allied government agencies.
Our aim is to collectively develop new approaches and embrace iwi and community aspirations as we play our part in protecting and restoring our beautiful country.
