Haunani is one of the Hawaiian feminine names — central to traditional Hawaiian Indigenous heritage. Hawaiian feminine name reflecting Indigenous Hawaiian heritage.
Haunani does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Haunani reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
