More than 400 Christmas posies have been delivered to Mount Eden Prison inmates, after the practice - banned this year as a security risk - was reinstated.
The delivery by the Quakers has been made every year since World War I.
The prison annouced this month that it was ending the tradition, saying it posed a security risk, but that was overturned after the Department of Corrections national commissioner asked them to reconsider.
A Quakers spokeswoman, Linley Gregory, said the team started working at 9am to ready the flowers for midday delivery.
She said the flowers had passed through the x-rays and the sniffer dogs just fine, and the delivery had been successful.
"For us it's important because it's realising a concern people had after the First World War.
"People who had been imprisoned themselves because of their stand against war - they saw a need to make prisons a bit friendlier and kinder, and this is just one of the many things over the years they've done."
Ms Gregory said that for the first time other groups had offered to help this year.
