It was a clear sky, no moon, I was 20 kms from this huge electric green light bulb that appeared in the nothern sky - from where I was standing on the shores of Lake Taupo, NZ, fishing for trout.

This light was very wide; I held up my hand and at full arms length; the light was as wide as my flat palm - 100 mms. 
It floated down with very small red sparks being ocassionally emitted from the 'socket' end of this bulb shaped apperition.  It was described as 'space debris re-entering the earths atomosphere.  This is hard to believe because the light had a sizzor cut edge, not fuzzy or ill defined, like facing a torch light would appear.
I am a writer now and if you have any theories I would appreciate the possible relevance of your info. This all happened above a large geothermal power source near Taupo   
Thanking you in anticpation.

Peter I had to photograph using a flash and to get the effect I had to slant the camera so as to get the illumination that is inevitable over or about the green orb. The moon was not there as it was a moonless night. which made the appearance of this phenominal occasion astounding.
I will try the Taupo paper again and will forward whatever I find out.
I would only be able to imagine as to their response at that time being non-alarmist to some degree.

Definately I will send you what I can or cannot find - the moon is in the picture it is up in the right hand corner - it is so small in relation to this light you have perhaps dismissed it.
Witness indicates that the date of the sighting is approximate.  PD
