Allegations Whangarei MP Shane Reti asked a Northland advocacy group to quieten down until after a byelection have been raised in Parliament.
The Pipiwai Titoki Advocacy for Community Health and Safety Group has been campaigning for several years to seal roads in its area, citing safety and health issues.
In a conversation with the group's spokeswoman, Alex Wright, on March 11 Dr Reti allegedly said, "If we continue down the path we are taking then we will get nothing".
Dr Reti did not respond to messages by edition time but reportedly said he was trying to help the group, not bully its members.
A letter from Ms Wright to the MP after the conversation was tabled in Parliament yesterday by Labour MP and Transport Spokesman Phil Twyford. Ms Wright said Dr Reti was responding to emails from a member of the group threatening to blockade a road. "His manner was not threatening but was just telling me that we needed to pull our heads in," Ms Wright said.
