Well, when the telescope has a polar scope, just center the +6.9 star BQ Octantis which is only 10' off the pole.
I did this often, allowing 4 minutes exposure with 600mm FL with pinpoint stars without guiding. No lasers required.

Several people have been arrested in the last few weeks alone for using them.

Presumably, powerful lasers are allowed in New Zealand ? In the EU there is a 5mW maximum limit.
