What type of rug would you put on a clipped Kaimanawa who lives in Auckland, New Zealand? As in how heavy eg 100g 200g etc.

It depends on the individual horse. I agree with Ashleigh, I would start with 200g but check the horse regularly and if it's cold, go heavier, if it's hot, go lighter! Some horses like the cold more than others so you may find that 100g is perfectly fine. Let your horse decide ☺️
200g but take it on and off according to the weather
