Lyttelton Service Station is a mechanic on Canterbury Street in Lyttelton, the port settlement on Banks Peninsula below Christchurch, with a 4.4 Google rating.
A good mechanic is worth finding before you need one in a hurry. In New Zealand that often starts with the warrant of fitness: a regular check that catches worn brakes, tired tyres and small faults while they are still cheap to fix. Steep hill roads like those around the harbour are particularly hard on brakes and clutches, and salt air finds any weakness in a body or exhaust, so locals tend to bring cars in at the first odd noise rather than the last. On a visit, expect someone to explain which repairs are urgent and which can safely wait.
For Lyttelton drivers, whose every trip out of town begins with a climb, having a mechanic on Canterbury Street is no small thing.
