Toni Street is calling for a change to the country's "outdated" adoption laws.
The TV and radio personality has revealed she and her husband are yet to officially be deemed parents of their biological son, who was born via surrogate in August.
Street's friend Sophie Braggins carried baby Lachlan.
The broadcaster shared an Instagram post of a change.org petition calling for change to the Aoption Act of 1955, which it calls "outdated for modern New Zealand".
"It is incredibly hard for loving parents to adopt in this country and our vulnerable children deserve better. I've also experienced first-hand how outdated the process is for surrogacy... we are still waiting to legally adopt our biological son," Street captioned the post.
It clearly caught the eye of Prime Minister Jacinda Ardern, who commented on the post last week while on a UN trip to New York.
"The Adoption Act is well over 50 years old and definitely needs fixing. It's on our work programme!" Ardern wrote.
"Thank you for this, so appreciate you responding," Street replied.
Street told ZB on Tuesday morning the "entire process is very, very slow".
"The process to even get the child in the first place was ridiculous. Oranga Tamariki has had to come to our house twice to check that we are fit parents, they still have to do this again at some point," she said.
"We are trying to adopt our biological son, it's not like we have used another person's egg or sperm. It is the most straightforward case you could imagine, [but] eight weeks on we are still waiting to get our date with the Family Court."
The Labour Party promised to "overhaul" the Adoption Act during their 2017 election campaign.
"The Adoption Act is now over six decades old, and is badly in need of overhaul," the party's policy stated.
"To address issues that have arisen in the operation of the existing legislation Labour will review and reform the adoption system in New Zealand."
