The Newman–Tamburino spherical metrics are investigated using the homothety formalism of the author's previous work (2002 Class. Quantum Grav. 19 259) and shown to always admit a homothety. The analysis also reveals that these metrics always admit a Killing vector, correcting a claim by Collinson and French (1967 J. Math. Phys. 8 701). The limit form of the cylindrical Newman–Tamburino metric is also shown to admit a homothety.
