Pretty sure they are heated now. Not super warm, but definitely not cold. We did a cruise in July on Explorer, and people were swimming on the sail-away (mid-winter).

They x-ray your bags, they didn't open ours - just asked if they were soft drinks. I guess they could open the bags and check, but a very good chance they wont.

Just be aware that November, and really even early December is Spring. The weather will generally be good, but as mentioned above, it can be changeable. It can still be cold in all of NZ ('cold' in Auckland is anything below 15 degrees C in Spring) during those months, but at the same time, it could also be quite warm. We do say here in Auckland though that if you don't like the weather, just wait 30 minutes and something different will come along 🙂 February and March are generally the best months for warm settled weather.
