Just got one now, same as others had, google and found this thread, so just blocked it.

I got the call too but hung up before I could answer. I am a Solar Zero customer so might be them

keeps ringing 3 times a day early in the morning (7am), afternoon (12pm) evening (7pm).
I don't know anyone in Nelson.

Unknown - so don’t bother with this type of stray call. Presently like sales or bitcoin freebees just likely a scan.

Caller: Solar Zero

Yes this is Solar Zero

I think this is solarzero.co.nz

Voicemail that was left seemed a accident foreign people speaking about inappropriate things in English on the voicemail that was left

Rings all the time, i don't know anyone in Nelson, is it that solar city place?

2 calls from this person, they dont leave a voice message or anything.

This call came up from Nelson, I tried to answer it as thought my it was my insurance provider. When I answered the call I heard a woman voice briefly and then she hung up. I saw a comment on here about Solar, I have made solar enquiries so maybe it was that. Could be a valid number, I will see if they call back again.

I got it this afternoon and showed up as Nelson on my phone.
Have now blocked it.

Rang but did not leave a message. Don't have any South Island landlines in my contacts and have Googled it and can't even find what area it's from.

Phoned me about solar panels from an inquiry that I had made -I never made an inquiry
