The NSW Department of Primary Industries has upgraded its varroa mite eradication focus.
It will now move into the euthanasia and disposal phase of the response, having successfully conducted extensive surveillance around the perimeter of the zone, the department said during the weekend in a statement.
NSW DPI chief plant protection officer, Satendra Kumar, said the goal of the varroa mite response is to fully eradicate the mite, which requires taking actions that will significantly reduce the likelihood of any further natural spread around the known infected sites.
"The next phase of Varroa mite eradication includes the Newcastle, Port Stephens and Central Coast regions," Dr Kumar said.
"Eradication activities will begin on the outer edges of the Varroa mite eradication red zones and work towards the centre."
The first major operation is taking place around Calga on the Central Coast in the southern end of the eradication zones.
The department said affected beekeepers would be contacted by the local response team to confirm details of their hives and discuss hive disposal and reimbursement options.
Under the eradication phase, all hives within the eradication zone will need to be euthanised, including those hives which are free of varroa mite.
Eradication has been underway for some weeks at infected sites and at many hives within close proximity to these.
"To achieve full eradication, it is critical that we look beyond just the known infected sites and eradicate any potential future hosts where incubation of the parasite may be happening," Dr Kumar said.
"Our extensive surveillance and awareness of the natural spread pattern of the Varroa mite provides the basis for determining the eradication zones, marking a 10km radius around all infected sites, in order to reduce the potential for further natural spread."
A reimbursement program has been made available to support registered commercial and recreational beekeepers affected by eradication operations as part of the Varroa response.
Authorised officers will provide impacted beekeepers with details of how they can apply for reimbursement.
The varroa mite reimbursement program is administered by the NSW Rural Assistance Authority.

There are now 99 infected premises in NSW.
Two additional infected premises were detected on Thursday, August 18, at Mayfield in the Hunter region and Calga on the Central Coast, both close to existing infected premises.
All confirmed cases either have clear links to existing cases or are geographically related, the department said.
Dr Kumar said an updated emergency order was published on Friday, August 19, which included allowing a registered beekeeper to split hives within a single premises, and simplification of movement of honey supers in each zone.
"I strongly encourage all beekeepers to keep up to date with what they can and can't do in each emergency zone by visiting the DPI website, and checking daily updates through the website and the NSW DPI biosecurity Facebook page," Dr Kumar said.
