Auckland's best-known Anglican Church is shutting its doors for three months after Sunday morning's service so it can undergo a facelift.
The Holy Trinity Cathedral in Parnell has hosted the funerals of Sir Edmund Hillary, Sir Paul Homes and Sir Paul Reeves.
More than 100,000 people attend the church each year.
The renovations will include the removal of a bridge which divides the Cathedral building so an old organ can be removed, and the process will also increase seating capacity.
There will also be a new chapel to seat 120 people, and a covered walkway linking the Cathedral to St Mary's Church.
Auckland ratepayers have contributed $3 million towards the $13 million project, which will be completed in 2017.
Services will be held at St Mary's during the three-month closure.
