"This is an opportunity to start engaging the young people of Tauranga. It's about finding out their expectations of what a museum should be and involving them in the process," she said.
McGregor, who attended Tauranga Boys' College, had more than 20 years of museum, gallery, exhibit and visitor design experience.
He said having a museum in Tauranga would show a statement about the "development and maturity" of the city.
McGregor left Tauranga in 1989 and moved to Wellington to pursue his design career.
With so much growth the city was experiencing, McGregor said it was important to support local talent and keep it in the city.
The pair had worked on a number of Te Papa's most successful and well-known museum exhibitions including Bug Lab and Gallipoli: The scale of our war.
Skachill said working to develop the Gallipoli exhibition, which was a collaboration with Weta Workshop, was "incredible".
Convener of Taonga Tauranga, Peter McKinley, said through co-creation the pair had actively involved the people they were designing for, to create some of Te Papa's most loved museum experiences.
"Their story is a great example of how the Tauranga museum could evolve."
