The CDHB said 101 patrons had been vaccinated so far, with more clinics on Friday.
It put a call out on Tuesday telling anyone who dined at the well known St Asaph St restaurant, owned by celebrity chef and MasterChef NZ judge Josh Emett, on January 15 and 17 to come forward after the hepatitis A scare.
Its community and public health team said people who ate at Madam Woo on those days may have been exposed to hepatitis A.
It offered an urgent hepatitis A vaccination to diners who had no previous immunity to the infectious liver disease.
