Broderick was sentenced in December to six months' home detention, with six-month post-release conditions but it's unclear if he is still serving that sentence.
"Police are keeping an open mind about his whereabouts and believe he may be anywhere in the North Island," a spokesperson said.
"Broderick should not be approached and anyone who sees him should phone 111.
"Police are also appealing to Sean Broderick to hand himself into police."
Anyone with information about his whereabouts or possible sightings should contact police on 105, quoting file number 210129/1368 or Crimestoppers anonymously on 0800 555 111.
