(b) External lights used solely for the lighting of the approaches to the premises may be used at night provided that no light is emitted above an angle of 5 degrees below horizontal, and that the power of each light-source does not exceed 60 watts.

7. External lights may be used at night for the lighting of railway shunting yards and tracks, Harbour Board wharves, ships being loaded or unloaded, ships being built or repaired, and air ports, so long as the lights are shrouded and reduced in power in accordance with orders given by the Controller in respect of any particular lights or class of lights.

8. At Waitemata Harbour, Port Nicholson, Lyttelton Harbour, and Otago Harbour, and at Greymouth, Westport, Oamaru, Timaru, Picton, Napier, Gisborne, and New Plymouth, all wharf working lights and railway yard lights shall be screened so that as far as is practicable without interfering unduly with working conditions each source of light and its shroud cannot be seen from any part of the harbour.

9. With the prior approval of the Local Lighting Controller, and subject to such conditions and restrictions as he may impose in each case, open spaces situated within any coastal area, not being spaces visible from the open sea, and not being situated within areas visible from the open sea, may be lighted at night for the training of any branch of the Emergency Reserve Corps, so long as every light-source is adequately shaded and so reduced or limited in power as to avoid any possibility of sky glow.

10. Open spaces situated outside any coastal area may be lighted at night for any purpose, so long as the power of the lights is restricted to the extent necessary to prevent sky-glow being visible from any point ten miles or more out to the open sea.
