Staphylococcus argenteus (SARG) was discovered in 2009 as part of the aureus (SAUR) complex and has been documented from various locations worldwide. In this article we describe genomic features five strains SARG found Christchurch, New Zealand. Isolates were first detected 2019 using MALDI-ToF identification, their identities confirmed whole genome sequencing (WGS). Genomic features, including antimicrobial resistance markers virulence factors compared to other sequences NCBI GenBank well-characterised SAUR. Four isolates belonged ST2250 one isolate ST2793. Phylogenetic analysis based on core revealed that all 5 phylogenetically distinct with four clustering clade. Three contained staphylococcal cassette chromosome mec (SCCmec) type IV 2Bc, harbouring mecA gene conferring beta-lactam antibiotics. All shared many genes global SAUR isolates;however, no TSST-1 or PVL pathogenic detected. This publication contributes additional data occurrences SARG.
