Kaihautū o Puni Arowai (KOPA),
Our Leadership team

Mā mua ka kite a muri, mā muri ka ora a mua.

Those who lead give sight to those who follow, those who follow give life to those that lead.

Kaihautū o Puni Arowai KOPA

Our Leadership team is known as Kaihautū o Puni Arowai (KOPA) where:

  • Kaihautū refers to the head of a department or agency.
  • Puni refers to a department or group of people.
  • Arowai speaks to the focus of the kaupapa of Taumata Arowai on the wai as a taonga, and our focus to put wai mauri, wai mana and wai ora at the centre of everything we do.
  • KOPA is the space in front of a house and also the floor space in the left corner on entering a wharenui – normally this is the place where the local people of the marae sit and sleep. This refers to our Leadership team being at the front, connecting with our people, the people we serve and those we work with to deliver our kaupapa.

Nō Engarangi ōku tipuna
I whānau au i Ghana
Heoi anō, i tipu ake au i Taranaki
He pūmahara nui ōku mō te wāhi whakahirahira o Taranaki
Ko Taranaki te maunga
Ko Waiongana te awa
Ko Te Ātiawa te iwi
I whānau aku tamāhine ki Taranaki
Kei Te Whanganui-a-Tara au e noho ana ināianei me tōku hoa rangatira

Ko te whare e hanga te tangata, ko te tangata e hangaia e te whare
He uri au nō Taupiri, hoea te waka o Tainui, riporipo rere ana te wai o Waikato
Tini ngā tātai o Tainui
Tau mai ko Ngāti Wairere e mihi ana
He uri au nō te whānau o Te Amo
Ko Katy Te Amo tēnei

Nō Kotirana okū tipuna
I tipu ake ahau i Manurewa, ki raro te marua i te iwi o Te Wai o Hua
No reira
Kō Matuku-tururu te maunga
Kō Waikato te awa
Kō te Whanganui o Manukau te moana
Engari, ki Wainuiomata ahau, e noho ana

After serving 10 years in the Royal New Zealand Navy, Ray began his public service career as a barrister and solicitor before developing his skills as a maritime investigator at Maritime NZ. Ray then went on to gain significant experience in developing and leading regulatory teams at the Environmental Protection Authority and Waka Kōtahi. Ray says that his background in law has provided him with a bunch of foundational and transferable skills that he applies daily in his regulatory roles.

Through his career Ray has gained experience across the full spectrum of regulatory activities from policy setting, carrying out frontline activities through to prosecutions, and has worked under the Health and Safety, Maritime Transport, Marine Protection, Hazardous Substances and Rail regulatory frameworks. Ray has also been a keen participant in the development of G-Reg and its predecessors along with numerous regulatory colleagues.

"I have a strong public service ethic and have been privileged to have been given the opportunities I have had to work for better outcomes for Aotearoa. Working for Taumata Arowai is an awesome opportunity to stand up a regulator that will positively impact the lives of every New Zealander as well as contribute to the health of our environment through giving effect to Te Mana o te Wai. I’m excited about the responsibility I have for ensuring that we design and deliver our regulatory functions in a way that works for the drinking water industry and works best for Aotearoa."
