Yes. All patrons must be 18 or older. Bring valid ID for entry. As for dress code, Malbas is relaxed but generally expects casual nightlife attire. Streetwear (jeans, tee shirts, dresses) is fine. Beachwear, jerseys, or sport teamswear are usually discouraged. Shoes are required (no bare feet). The staff may deny entry for overly muddy or inappropriate clothing. In general Kiwi club etiquette applies: be tidy and presentable. If in doubt, aim for smart-casual: fresh (not covered in sand or something), but you don’t need anything formal. On themed nights (e.g. fancy dress), suggestions will be advertised. Otherwise, just wear what you’d wear to a normal night out dancing in Nelson.
