Religious banner in sky should have been banned

On a lovely winter’s Sunday morning on January 4th, my family and I were exposed to a aeroplane souring the sky over Nelson. On closer examination the plane was trailing a religious message.

I found this very invasive and offensive to my family values. The plane must have been flying in the area for at least an hour and a half or more.

How did this happen? Surely permissions were granted for this but why on a Sunday morning and for such an extended time?
