Due to enter service in couple of years. Back in July 2018, the New Zealand government announced the purchase of four P-8As, to begin operations in 2023. Four P-8As were ordered in March 2019, completion is expected by June 2020. This purchase also meant that the main base of operations had to move from Hobsinville/Whenuapui Air Base to Ohakea Air Base, and even then infrastructure has to be built to accommodate the new aircraft.
So here are a couple of photos of the construction happening at the RNZAF Base Ohakea with all the new construction and infrastructure being being built for the P-8 Poseidon's.
