Community tensions will surround the release of convicted double-murderer Mark Lundy from prison, and Palmerston North does not want him back, the city's mayor says.

Supporters of Mark Lundy, who will be released from prison next month after serving more than 23 years for murdering his wife and daughter, say his fight to clear his name is continuing.

The 66-year-old was twice found guilty of killing his wife Christine and daughter Amber in their Palmerston North home in August 2000.
