The Returned and Services' Association is encouraging all Kiwis to take part in first flag referendum - even if voters want to keep the current flag.
The majority of Returned and Services' Association (RSA) members supported the current flag, national president BJ Clark said.
"There are different views in our organisation, just as there are in every group in New Zealand, but the vast majority of members agree with the RSA taking a stand on this issue," he said.
The ballot paper would ask people to rank the five alternative flag options, but if voters wanted to keep the current flag they should write this on their paper, Mr Clark said.
"...it is their right to express that point of view."
