Ferry Terminal is a car wash at 13 Foreshore Road, Bluff, by the port at the southern end of State Highway 1, holding a 4.2 rating from 28 Google reviews.
Near the sea, washing a car is as much about protection as looks: salt spray works into wheel arches, sills and the underbody, so the vehicles that stay sound are the ones rinsed regularly rather than polished occasionally. A good wash pre-soaks to lift road grime and dried-on insect splatter before brushes or high-pressure jets take over, and a careful hand-dry afterwards prevents the water spots that appear quickly in coastal sun. Winter and spring are when washing really earns its keep, with sea mist and wet roads doing quiet damage between cleans.
For drivers heading to the Stewart Island ferry or making the run up to Invercargill, it sits handy on Bluff's foreshore.
