Outgoing Commissioner of Police Mostyn Mangau has formally ended his six-year tenure at the helm of the Royal Solomon Islands Police Force (RSIPF), during a farewell parade at Rove Police Headquarters on Wednesday, 31 December 2025
This means he will not be returning to the role as leadership transitions to Acting Commissioner Mathias Lenialu.
During the ceremony, he urged the Acting Commissioner to lead with fairness, wisdom and a strong commitment to service.
“The challenges ahead are real, but so too are the opportunities to build a stronger and more resilient police force,” Mangau said, describing his departure as the passing forward of responsibility after years of institutional reform.
He said the Acting Commissioner now inherits not only command of the RSIPF, but also the hopes of Solomon Islanders for peace, security and justice.
“I recall the words of my predecessor—that leadership is about continuity and service, not personal glory,” Mangau said.
“Today, as I step aside, I echo that same sentiment.”
Prime Minister Pays Tribute
Prime Minister Hon. Jeremiah Manele paid tribute to Mangau during the parade, acknowledging his leadership of the RSIPF from 29 November 2019 to 31 December 2025.
The ceremony was attended by Police Minister Hon. Jimson Tanangada, RSIPF officers and ranks, senior government officials, and representatives of donor and development partners from the Ministry of Police, National Security and Correctional Services.
“Commissioner Mangau has led the RSIPF through both routine duties and challenging times with professionalism and perseverance,” Prime Minister Manele said.
He noted that under Mangau’s leadership, the RSIPF successfully provided security for major national and regional events, including the 2023 Pacific Games, the National General Elections, and the Pacific Islands Forum Leaders’ Meeting—efforts that helped maintain public confidence in national institutions.
The Prime Minister also highlighted Mangau’s role during the COVID-19 pandemic, when police supported border management, quarantine enforcement and public order, while continuing essential policing services across the country.
A key milestone of Mangau’s tenure was the launch of the RSIPF 10-Year Strategic Direction, which Manele described as a critical roadmap for reform, capability development and improved service delivery over the next decade.
Legacy and Transition
Reflecting on his time as Commissioner, Mangau said the RSIPF had matured into a more trusted and legitimate institution, anchored by clearer strategic direction and strengthened professionalism.
“Now, as I prepare to hand over responsibility to the Acting Commissioner of RSIPF, I look back with gratitude and pride at what we have accomplished together as a team,” he said.
Prime Minister Manele congratulated Acting Commissioner Mathias Lenialu on his appointment and encouraged him to build on the strategic foundation laid by his predecessor.
He also thanked RSIPF officers, the Ministry for Police, National Security and Correctional Services, donor partners, and Mangau’s family for their support throughout his tenure.
Mangau’s departure closes a significant chapter in the RSIPF’s leadership, as the force looks ahead to consolidating reforms and sustaining public trust under new command.
