The Auckland City Mission is about to begin the enormous logistical exercise of relocating its entire operation.
The city mission will tomorrow begin shifting to a temporary site so its original building on Hobson St, where it has been since 1980, can be upgraded.
Its accommodation, food bank, medical centre and other services will be based at Union Street, about 1km away, until the $90 million redevelopment is completed.
Around 400 homeless people have the Hobson St site listed as their official address.
"There will be some grief, considerable grief as people leave Hobson St after all these years," said City Missioner Chris Farrelly.
