Its moment was 2020, when 29 babies were given it. In 11 of the years between, the name fell under the 10-birth floor and the registrar published nothing — those years are the marks along the base of the chart, not gaps in the name's use.

How Ihaia's figures are worked out

  1. Counts come straight from the registrars: the US Social Security Administration (1880–2025) and the New Zealand Department of Internal Affairs (1900–2025). Nothing is scraped from another names site. The SSA files are the agency's own, retrieved from the Internet Archive's 2026 snapshot of ssa.gov (ssa.gov refuses automated requests); files unmodified.
  2. Ranks are computed against every name in that year's file, not just the ones this site publishes pages for — otherwise a rank would flatter every name we happen to list.
  3. The curve is drawn on births per 100,000 of that sex, not raw counts. Raw counts across eras are misleading: far more births were registered in 1957 than in 1890, so a flat count is a falling share.
  4. The reporting floor. Each registrar publishes a name only once it clears a threshold — 5 births of that sex in the US, 10 in New Zealand. Expressed as a share that threshold is itself a curve, and it is drawn on every chart here as the shaded band along the base.
  5. A missing year is a suppressed value, never a zero. Where the registrar published nothing, this site prints “below floor” or “<5”, the curve is broken rather than drawn across the gap, and the missing years are marked on the floor line. Ihaia was under the floor in 11 years of its NZ record.
share per 100,000 = births ÷ all births of that sex that year × 100,000
reporting floor (share) = 10 ÷ all births of that sex that year × 100,000

Ihaia in England & Wales

Ihaia does not appear in the ONS list for England and Wales. That means it was given to fewer than 3 babies in every year from 2019 to 2025 — not that it is unused there. ONS publishes only those seven years, so a name that had its moment in England before 2019 is invisible here however common it once was.
