Lakes District Health Board's Covid-19 vaccination programme began in February with Managed Isolation Facility workers and their household contacts.
The hub in Rotorua's Central Mall opened on March 16 and one opened in Taupō on May 28.
There had also been outreach clinics on marae, in drive-throughs and in aged residential care facilities, among others.
The 100,000 doses included first and second ones and represented almost 17,000 vials of the vaccine.
Meanwhile, the Bay of Plenty District Health Board recorded their 200,000th vaccination on September 15.
More than half of the Bay of Plenty's residents have received at least one dose of the Covid-19 vaccine, according to data from the Ministry of Health published on September 7, 2021.
New Zealand needs to get vaccinated now to beat Delta - and that's why NZME has launched The 90% Project. We want to help 90 per cent of Kiwis get vaccinated to save lives and reopen our country to the world.
