About this data: figures come from Department of Internal Affairs birth registrations for 1954-2025. The DIA only publishes a name for a given year when at least 10 babies were registered with it, so rarer names - and rarer spellings - are missing entirely, and a name can drop out of the record in quieter years. Spelling variants are counted separately, and counts reflect first names as registered.
