A recent editorial (ODT, 16.6.17) questioned some of the decisions made in controlling the flat oyster parasite Bonamia ostreae, since it was first detected in Marlborough in 2015.
The 2015 decision to allow the Marlborough farms to continue operating was made after a range of considerations. Scientific advice was considered, as were other factors such as geographic proximity to wild oysters, tidal currents and the impact on industry and local communities.
Our decision then was that strict controls were sufficient to stop the spread. Extensive testing shows Bonamia ostreae isn't in any areas close to Marlborough outside the controlled area. This indicates these controls have been effective.
The detection of the parasite in Big Glory Bay, Stewart Island, means the risks are now different, which is why we're removing oysters in both areas. This reduces the overall presence of Bonamia ostreae nationally, limiting the chance of further spread.
Work to remove oysters in Big Glory Bay has begun this week. Oysters will be uplifted, then securely transported to a landfill in Bluff for disposal. Care will be taken throughout all steps of the operation to prevent risk of further spread of the parasite.
The removal operation is a huge task and we are thankful for the support of the community and assistance from oyster farmers to make it happen.
The removal work follows a range of actions taken since Bonamia ostreae was detected in Big Glory Bay on May 24. MPI has set up a response team to manage the issue, put in place movement controls, engaged with affected farmers and the local industry and more.
We have established a field headquarters to provide support to Stewart Island farmers and others on the ground. Rushing this process could have had potentially disastrous consequences.
The discovery of a pest like Bonamia ostreae can have a major impact on people's livelihoods. It is important to us that we provide support for the farmers and communities involved.
We are offering operational assistance to farmers affected. We are also holding community meetings in Stewart Island and Bluff that will give local people the opportunity to ask questions and help us fine-tune the removal operation.
There are provisions for compensation under the Biosecurity Act relating to losses arising from the exercise of powers under the Act. The amount depends upon what losses are incurred as result of any direction by MPI.
Affected parties have to apply for compensation. MPI has been talking through this process with affected farmers and will be providing additional information and support.
MPI is committed to doing all it can to minimise the spread of Bonamia ostreae and to get the best result for New Zealand.
