The UNSC Dunedin is an auxiliary ship in-service with the UNSC Navy in the aftermath of the Human-Covenant War.
It was present amongst the support squadron, consisting of Bellesile, Glamorgan, and Port Stanley in the Zeta Doradus system when the Trevelyan Dyson sphere was brought into real space from slipspace in early 2553.
This auxiliary was likely named after Dunedin, the seat of government and largest city in the Otago Region of New Zealand.
