Origin
The surname "KAHAWAI" is believed to have originated from the Maori language of New Zealand. It is likely derived from the Maori word "kahawai," which refers to a type of fish found in the coastal waters of New Zealand, the Australian salmon or sea trout.
This surname is believed to have emerged during the early colonial period in New Zealand, when Maori individuals began adopting European-style surnames. The name may have been adopted by individuals or families who had a connection to fishing or lived in coastal areas where the kahawai fish was prevalent.
The earliest recorded instances of the surname "KAHAWAI" can be traced back to the late 19th and early 20th centuries in New Zealand. One notable person with this surname was Tame Kahawai, a Maori leader and activist who lived from 1865 to 1939. He was a prominent figure in the fight for Maori land rights and the preservation of Maori culture.
Another notable figure with the surname "KAHAWAI" was Rangi Kahawai, a Maori artist and carver who lived from 1932 to 2010. He was renowned for his intricate wood carvings and his contributions to the revival of traditional Maori art forms.
In the early 20th century, the name "KAHAWAI" also appeared in historical records related to the Maori Battalion, a military unit composed of Maori soldiers who fought in World War II. Several individuals with this surname were part of this battalion and served in various campaigns across Europe and North Africa.
Additionally, the surname "KAHAWAI" has been associated with various place names in New Zealand, particularly those related to coastal areas or bodies of water where the kahawai fish was found. For example, there is a small settlement called Kahawai near the Bay of Islands in the Northland region of New Zealand.
While not as widespread as some other Maori surnames, the name "KAHAWAI" remains an important part of New Zealand's cultural and historical heritage, reflecting the deep connection between the Maori people and the natural resources of their land and seas.
Demographics
Among Census respondents with the surname Kahawai, the largest self-reported group is Asian/Pacific Islander at 46.6%. The next largest groups are Two or More Races (33.1%) and Hispanic (13.6%).
The bar chart below shows how Kahawai bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Kahawai surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
