We are tracing movements of possible risk goods on to the affected properties as part of this investigation. This knowledge will enable any necessary measures to reduce the risk of new outbreaks.''
Oamaru-based farm consultant Richard Strowger said most people believed the disease had been contained.
People were now playing a game of wait and see to have it confirmed through the extensive tests ministry staff were running.
He said the feeling in the community about the new disease was one of ''understanding'' rather than frustration, which previously existed.
''It's no different to when someone is diagnosed with cancer - initially grief and then you have to wait.''
He praised the ministry for its work to this point and hoped communication would remain open.
While the ministry was quick to tell the public it might never know how the disease got through border controls, he said it was a question the community wanted answered.
''All that sort of stuff, but we're not at that stage yet.''
