"However, we are saddened by the lack of professionalism given by the New Zealand police and the way that they have handled this case based off circumstantial evidence and incriminating and framing an innocent man who has never met George Taiaroa and could not ever identify George prior to this case.

"Quinton Winders is an innocent man and sadly with great regret this is not closure for either family at this time.

"We as a family will continue to fight for my brother's freedom and this miscarriage of justice that has occurred. We hope that justice will prevail.

"We would also like to just acknowledge all the public support we have received as a family."
