To help prevent hitchhiker pests travelling to Chatham Islands regular air and shipping services receive biosecurity checks and treatments. Pests common in other parts of New Zealand, including wasps and invasive ants are not present on the Chatham but are regularly intercepted and on freight.

SPS Biosecurity was contracted to carryout delimitation surveys and mapping for Great Willowherb in North Canterbury, New Zealand. This highly invasive pest plant easily disperses by both seed and aggressive rhizome growth, allowing it to establish in pristine wetlands.
The SPS team searched wetland areas for this pest plant and conducted follow up inspections as part of the investigation and tracing process.

Australian forest and timber insects are common introductions to New Zealand
New Zealand trees and forests are only a four-hour flight away from Australian pests and diseases.
These can either be simply blown across the Tasman Sea or arrive as ‘hitchhikers’ that manage to evade the Ministry for Primary Industries strict border biosecurity.
Some of the most common insects that SPS Biosecurity find during detection surveys, include wood-borers and foliage feeders of eucalyptus.
Over the past five years two new paropsine beetles, Paropsisterna beata and Paropsisterna variicollis have been detected. Both the adults and larvae of these types of beetles feed on eucalyptus foliage. Established pests that have been in the country for a while, also continue to be detected by the team in new regions. The gum emperor moth Opodiphthera eucalypti and wood-boring longhorn beetle Epithora dorsalis, are just two examples that continue to increase their range across New Zealand.
The most recent new introduction on eucalyptus is the red gum lerp psyllid Glycaspis brimblecombei. This was found by one of our directors in North Canterbury in 2017.
Island Biosecurity Plans
Islands usually have unique flora and fauna and are also often free of many pests found on larger land masses.
SPS Biosecurity specializes in developing border biosecurity plans for islands. We have a good track record of managing both marine and terrestrial biosecurity risks related to human activity.Recently SPS has developed Biosecurity and Quarantine Plans for construction companies, consulting engineers, aid and development programmes, shipping companies and Government agencies.

Cocoa Plantation Pest Survey - Western Savai'i Samoa
SPS Biosecurity recently conducted a tree health and pest assessment for the cocoa sector in Western Savai’i, Samoa.
Aerial UAV assessments and follow up ground surveys looked at the influence or potential negative influence that pests and diseases might have on cocoa Theobroma cacao. The tree health symptomatic survey was conducted at seven plantation sites across Western Savai’i and one cocoa nursery. The survey confirmed that pest and disease influence was generally low and the overall number of introduced pest species and new encounter interactions was also low.
The ‘heirloom’ Trinitario variety of cocoa grown on Western Savai’i is known to suffer significant losses due to pests in other countries. Stopping new pest agents arriving will be an important part of building resilience for farmers and the growing sector.
SPS Biosecurity has also developed a Biosecurity Plan to address biosecurity risk pathways and reduce the chances of ‘hitchhiker’ cocoa pests arriving.

SPS Biosecurity managed the border biosecurity for a $53m wharf development on the Chatham Islands
For the $53m rebuild of the Waitangi wharf on the Chatham Islands SPS Biosecurity worked with the construction group; Memorial Park Alliance, Chatham Island Council and Environment Canterbury to ensure new pests were not transported to the Islands. The biosecurity management plan catered for an expected 7000 tons of freight to be shipped by sea and included both marine and terrestrial biosecurity.
World Forestry Congress - South Africa
Director, Paul Bradbury travelled to Durban to attend the 14th World Forestry congress, Durban South Africa. This is was the first time the FAO sponsored congress had been held on the African continent and attracted over 4000 delegates. Although impossible to attend many of the concurrent sessions an effort was made to participate in presentations and workshops involving biosecurity, market access, standard setting, agro-forestry and ecosystem services provided by forests.
The international view on the role of forests, their preservation and restoration is quite different to New Zealand approach. In New Zealand, preservation and the exclusion of economic activities in natural forest areas is favoured but this is quite an alien concept elsewhere in the world, where communities live in and interact with their forests. The FAO acknowledges that forests are vital in providing ecosystem services that include or enhance agricultural activities and other sustainable uses. As good conservation outcomes are difficult without economic resilience. (How refreshing)
