Your child is more likely to want to write at home if they see you writing. Try to involve them in real contexts for writing, e.g., shopping lists, thank you letters, cards, emails to family. Have writing tools and materials available for your child to use, e.g., whiteboard and pens, blackboard, paper, pens and pencils, keyboard.
The Ministry of Education’s website is an excellent resource and has lots of writing ideas suitable for each year group.
