Leaders of the Mount Roskill Evangelical Fellowship church say they want their entire congregation of more than 300 people to have been re-tested for Covid-19 by the end of today.
There are 45 cases of Covid-19 linked to the church, a sub-cluster within the bigger Auckland outbreak.
By yesterday morning, around two thirds of the church's members had re-tested for Covid-19.
