An upgrade of navigational equipment at Blenheim Airport means New Zealand Post will be diverting its early-morning mail flight through Nelson.
Nelson Airport chief executive Kaye McNabb said the temporary arrangement would see the Fokker Friendship aircraft used by NZ Post arrive in Nelson at 6am rather than the usual 3am schedule it followed.
Mrs McNabb said although the usual schedule is for arrival in Blenheim about 3am each day, Nelson Airport had successfully negotiated a change in the schedule to minimise the effect of noise on the surrounding residents.
Mrs McNabb said the changed schedule will have a "significant impact" on NZ Post.
There would be the inevitable flow-on effect through the distribution and delivery chain.
She said the team at Nelson Airport was pleased that the operator had been so willing to co-operate for the benefit of local residents.
The project in Blenheim is expected to be completed in less than three weeks after which the Fokker will return to its normal route and schedule.
The aircraft is expected to remain at Nelson Airport from 6am until 9pm each day for the duration of the works at Blenheim Airport and will be parked across by the HNZ terminal.
Nelson Airport noise boundaries are set in the Nelson resource management plan to provide operational protection for Nelson Airport and minimise disturbance to residents.
The plan acknowledges the airport as a 24-hour operational facility but includes penalty noise measurements for night flight operations as a limiting measure.
The takeoff and landing noise measurements for a Fokker 27 are close to the "single event limit" in the plan between midnight and 6am.
