Bowkett, who went to high school in Rotorua, was a senior leader with 21 years' experience across the public and private sectors, the statement said.
He had a background in commercial advisory, infrastructure investment, system performance and influence, departmental financial management, economic development and oversight of complex funding systems, it said.
Department of Internal Affairs local government deputy chief executive Michael Lovett said Bowkett had the "experience, knowledge and mana" to help deliver the reform programme.
"Hamiora has considerable experience working with whānau Māori and iwi across the health and social sector systems and in the Māori development space, which will be invaluable in ensuring te ao Māori perspectives are respected in the water reforms.
"He joins the team from Te Puni Kōkiri, where he is Deputy Secretary Strategy, Finance and Performance. Hamiora has also worked at partner and executive director level at PWC and EY."
Lovett said New Zealanders needed safe, reliable drinking water, wastewater and stormwater - the three waters services.
"We depend on these for the health and wellbeing of our communities and our environment. Local government is facing significant challenges in managing these services," Lovett said.
"To address this, the Government is progressing reforms so that three waters services will be provided by four publicly-owned entities from July 2024."
