Birth question

My doe started nesting inside her nesting box Saturday evening/night and is constantly adding to her nest daily (hay and hair) Still no kits. This will be my first litter in a long time as I just got back into meat rabbits after about a 12 year break. How long should it be until I can expect kits? I thought it was 1-3 days after nesting started but apparently I was wrong. She’s a regular New Zealand doe.
