Objectives: To determine the relationship between New Zealand isolates of antibiotic-resistant Streptococcus pneumoniae and internationally widespread resistant clones.

Methods: Fifty-nine isolates representing both invasive and non-invasive pneumococci from multiple locations, serotypes and years were analysed by multilocus sequence typing.

Results: Major international clones, including Spain23F-1, France9V-3 and Taiwan19F-14, were found to be present in New Zealand. A one-allele variant of the Taiwan19F-14 clone (aroE 15→4, ST 271) was particularly prominent.

Conclusions: Antibiotic-resistant pneumococci have not evolved de novo in New Zealand, but were introduced to the country during the early 1990s.

Keywords: S. pneumoniae; PMEN; MLST
