Hi Tracey
The more dark sky the better. – Unfortunately the opposite is going on in Christchurch with the new super bright 4000 Kelvin LED road lights being installed everywhere.
The observatory in Kaikoura seems to be at no. 2 Austin Street, Kaikoura where a 20 Inch telescope is installed. The Kaikoura Art Society Incorporated is registered under that address. Contact details for the Kaikoura Art Society: Larry Field, email larryfield14@gmail.com, Ph. 022 319 7090 or 03 319 7090. I can’t be 100 % sure whether Larry Field lives at 2 Austin Street, but he most likely knows who is.
Good luck
Bert
