Brown will join Giles Motorsport, carrying the same #87 he sports in Supercars.
Last year’s Supercars champion will be one of 17 entries in the open-wheel series, which is a known proving ground for F1 hopefuls.
The Formula Regional Oceania Championship uses what it calls the FT-60, which is a Tatuus T-318 with a 2.0-litre turbocharged Toyota engine.
The Tatuus tub is common across Formula Regional categories, with the Formula Regional European Championship being the most high-profile series to utilise the carbon monocoque.
Brown’s first round in the single-seater series takes place at Taupo Motorsport Park on January 10-12 for the Taupo Historic Grand Prix.
