Necessities in SL (Freetown)

Hi All, I will be moving to SL for a year with my husband in August and wondering what kind of things I need to bring with me. I have researched a lot on climate etc but really with 20KG limit I need to be very choosy with what I bring and do not want to bring things that are not necessary but bring what may be hard to get or expensive to buy there. I am coming from New Zealand so used to a very mild climate.

Thank you in advance for any advice.
