Rua is also the number 'two' so could be well suited to a 2nd child. btw-(Tahi means the number one).
Hari as far as I know is not a colour - its meaning can be used as 'happy' though 'Koa' would be more appropriate. The use of Hari as happy would be in the context of 'happy birthday or happy anniversary'. Hari is a verb used in the meaning of taking/carrying something.
There is no 'y' in the maori alphabet, so the word/name Typihi would be spelt Taipihi. Which the meaning of would probably translate as 'Seagrass'.

I`m not saying you cant say, spell or pronounce a name anyway you want, but just want to help bring more understanding if those mentioned above were to be considered as Maori names.

BTW - Anaru is a transliteration of the name Andrew


The Maori names here I listed are just ones I've heard. It was a baby name website that had those meanings. Thanks for straightening it out
My SIL's uncle was Taipihi, but I've got no idea how it was spelt. Just that it was shortened to Pihi for my neices middle name.

I also know an Atu & I think its Ruki, but not sure.
