When is the best month to plant young Brussel sprouts plants so they mature in the colder weather?I am in Auckland

We have had Brussels sprouts growing in the community garden, would be better to plant them in cooler months or plant them just before the cooler months so we can harvest them. Brassicaceae same as cabbage and Broccoli, cauliflower to avoid the cabbage moth from eating the leaves? we don't like to use chemical sprays. All natural.

My Brussels sprout seeds are 175-200 day to maturity. I have tried to start in doors and plant out in June in a mostly shade area, the last 3 seasons, but have never had sprouts develop. I figured it was because we have been having too warm weather, and maybe not enough sun? This season I started in January indoors, and will put them out in March with some frost protection, with more sun. Thoughts?
