In 1991, when he was a Colonel, he replaced Colonel Lima Dataona as local commander on Bougainville Island, during a civil uprising. Security Challenges described him as a "hardliner". It said he led an unauthorized landing on Bouganville, that was counter to an interim ceasefire Papua New Guinea's civilian leadership had negotiated with Bouganville rebel forces, and disrupted their attempts to reach a lasting Peace Agreement. Nuia was suspended, after he publicly criticized the Minister of Defence.
