The New Moon rises with the sun.
It is 9:00 am of the next day in New Zealand.
10 AM same day
You can say "good night" when it is your day time, if you are talking to a person who is in a country where it is night time. When it is day time in Ireland, it is night time in Australia and New Zealand, and other places.
5.30 pm previous day
12:00 midnight
at ABOUT 7:40/30am (This is for England NOT any other contries that have a different time)
It's the day after yesterday, or the day before tomorrow. Any other answer will be wrong in a few hours because New Zealand is not frozen in time.
The new moon rises about the same time that the Sun does.
