The next NSW Labor general secretary will be banned from seeking elected office for five years, with the role to be "fully professionalised" and subject to annual performance reviews.

Federal Opposition Leader Anthony Albanese announced on Friday the party's national executive would intervene to impose structural reforms to the NSW Labor branch following recommendations of the Lavarch review.

Mr Albanese said the recommendations would be adopted "in full", to ensure "the mistakes of the past never, ever happen again" and will result in "real cultural change".

"This branch will be the most transparent branch of any political party in Australia," he said.
