Beneath the volcanic basalt and sprawling suburbs of Tāmaki Makaurau, Auckland, a silent, relentless war is being waged.

They are mediating a 150-year-old conversation between Victorian engineering, colonial botany, and volcanic geology. Each severed root is a truce, not a victory. The deeper truth is that roots will always find water.
