New Zealand’s biosecurity needs to be protected

New Zealand is free of many exotic diseases and their vectors. Effective quarantine and biosecurity procedures prevent the entry of these diseases or their carriers.

Sea ports at Timaru and Lyttelton, and Christchurch International Airport are potential entry points for these diseases.

Community and Public Health’s biosecurity-related activities at these locations includes:

• monitoring for exotic mosquitoes at ports and Christchurch Airport;
• responding to notifications of exotic mosquito interceptions and incursions;
• responding to ill passengers on international flights or visiting cruise ships; and
• inspecting ships for sanitary conditions and disease-carrying animals and insects such as mosquitoes and rats.

Community and Public Health are particularly focussed on mosquito-borne diseases and highly infectious diseases. Staff are ready to respond to any concerns that arise.

Responding to infectious diseases and other international events

The International Health Regulations (IHR) 2005 now take an ‘all hazards’ approach by including all events of a chemical, biological or radiological nature and are no longer just about responding to quarantinable diseases.

Christchurch International Airport Limited and Lyttelton Port of Christchurch are designated as Points of Entry under the IHR. This means they need to have met the required core capacities at all times.

Community and Public Health makes sure that sea ports and airports are ready to deal with a Public Health Emergency of International Concern (PHEIC) by:

• maintaining emergency response plans;
• assessing unwell international travellers and crew; and
• developing and maintaining relationships with key stakeholders.

Exotic mosquitoes pose a life-threatening public health threat

Community and Public Health staff conduct mosquito surveillance activities to prevent exotic mosquitoes spreading serious illnesses such as Ross River Virus and Dengue Fever in New Zealand. This involves:

• doing regular mosquito surveys at potential entry ports;
• responding to suspected exotic mosquito sightings or reports, and
• answering questions and complaints about mosquitos.

New Zealand is an appealing environment for exotic mosquitoes and it is possible that they could become established in the South Island. Introduced species are very difficult and expensive to get rid of once established. New Zealand has 12 native species of mosquito and 3 well-established introduced species.

Lyttelton is a busy sea port that receiving tonnes of high risk cargo every week (such as tyres, cars and machinery) from destinations such as Japan and other Asian countries. The port is near large areas of bush land – a mosquito-friendly habitat – and there is also a town very close.

Christchurch International Airport receives passengers and cargo from around the world. It has many sites that would suit container-breeding mosquitoes.

Fijian miracle water poses biosecurity risk

Released 20th March 2017

The Ministry for Primary Industries is asking travellers from Fiji to stop bringing “miracle water” into New Zealand if they want to avoid a stiff fine or treatment costs.

The untreated water is sourced from a natural spring in Dawasumu, and is claimed to have healing properties.

“Our concern is whether it contains waterborne diseases that could harm NZ’s freshwater aquaculture and natural environment – not whether it’s healing properties are real or not,” says MPI’s Manager North Passenger and Mail Craig Hughes.

“The locals may call it miracle water, but it is untreated, so it poses a biosecurity risk to New Zealand.”

MPI border staff have seized miracle water from nearly 500 air passengers arriving from Fiji since November.

“All arriving passengers are required to declare the water at the border. They have to pay for heat treatment costing around $60 if they want to keep the water. If they don’t declare it, they face a $400 fine or prosecution.”
