I don't pack liquid clothing detergent as hotel shampoo or body wash usually works fine. I guess that could be difficult if you dislike certain scents or are sensitive to SLS. Solid shampoo often has SLS which my scalp does not agree with but hands can survive a bit of.

I've never seen maracuja or marula oil offered as a condiment but olive oil probably qualifies. I try to pack all consumables together and declare it all as the fine for not declaring food (even if it would be allowed) is pretty hefty. Biosecurity is mostly interested in fresh fruit, vegetables, meat, fish, honey, and nuts (growth viable) but the form asks if you brought any food https://www.mpi.govt.nz/travel-and-r...-personal-use/ instead of a specific category.
