In the meantime, the family will be focusing on moving out of their rented accommodation, which has been plagued by mould, condensation and ventilation issues.
Ms Slack said the five children - including Evolet Vlamings, 3, Jada Slack, 11, Mya Slack, 9, Detroit Vlamings, 7, and Elexus Rupena-Tuoro, 2 - were already fighting over bedrooms in their new home.
"I am just thankful for the security we are going to get from having our own home. I'm not worried any more."
Mr Vlamings led a heartfelt haka at yesterday's dedication, which was attended by over 50 people including volunteers, friends and family.
"It was quite emotional to watch that, and a very proud moment," Ms Slack said.
The haka involved Habitat for Humanity Northland's Conrad LaPointe trading the key for the new home, which Mr Vlamings replaced with pounamu.
"I explained where I'm from [Waimamaku Ngapuhi] and that this whenua is ours now," Mr Vlamings said.
"It was a special moment for me and my family."
Mr LaPointe, Habitat for Humanity Northland's executive officer, was blown away to see the family so happy about starting a new chapter.
"It's days like this you realise this is what we work for.
"It was also wonderful to see so many people from the Whangarei community who have been directly involved [with the build]."
The build was started in November last year and was completed predominantly by volunteers.
