From Ngaire Small of Tahunanui, Nelson. Jan 8, 2014.
This mass of aerosol ‘fingers’ appeared early in the morning of Monday, the 6th of January whilst the rest of the sky was fairly clear. It hung in the sky, looking weird for quite some time and appeared to have originated from behind the city hills. It was rather spooky looking.
I sent the image to our local newspaper for comment, thinking that surely their reporters would have been intrigued? There has been no response yet. 
NORTHLAND NEW ZEALAND CHEMTRAILS WATCH 
These are chemtrails being manipulated with frequency, it is a method used For manipulating the jet stream and other weather.
Will be interesting to see what the response is from your local newspaper, Ngaire.
I am inspired by your example, and shall endeavor to share some of the bizarre anomalies from my area of North Canterbury with my local newspapers this year.
Looking at my own sky-watching images from January 6, 2014, I don’t have any exactly the same as your excellent photo above, but I do have evidence of very unnatural-looking cloud material with ripples, as well as startling colours like green, purple, pink and apricot which I would not expect to see in normal, natural cloud.
