First thoughts are I hope this is Visa related or something like that, don't want any Joey bad news :(.
They also had a March 1st show in Beijing and another in Hong Kong that have been cancelled. My guess is these cancellations are related to the virus. Their other concerts in the first week of March in NZ are still for sale. I suspect all is good with the band.
