Whangārei mayor Sheryl Mai said she could not believe the transformation of the back part of the Old Army Hall building.
She used the analogy of a caterpillar turning into a chrysalis and emerging as a "beautiful butterfly".
Mai thanked the members of the community who had given their time and energy tirelessly to work on the building and achieve so much in such a short period of time.
She also thanked One Double Five Community House's Carol Peters.
"We want homelessness to be a very rare thing, that's what we're aiming for. We want people to be in permanent rentals, we want people to own their own whare, that's what we want. This is a step on the way."
She made mention of the various funders and those who had made significant donations.
The centre is in part of the Old Army Hall and later Major Roberta Wilkinson shared the history of the building with those gathered.
Other speakers and local artists performed into the afternoon.
