Tania Nugent fondly remembers the warm welcome she received from her tambu, her mother's people, the Ahi.

The Ahi are the traditional owners of Lae, the second biggest city in Papua New Guinea and the country's booming industrial heartland.

Tania returned to her mother's homeland for a story about the challenges of balancing development and custom land ownership as the city of Lae expands and embraces economic growth.
