For almost a century, the Mason family have kept a closer eye on the weather than most people.
But now, at 94, volunteer Alan Mason of Feilding is looking for a successor.
Every morning Mr Mason checked his rain gauge, opened the hatch on his thermometer board, then went to his office and emailed the data to Niwa.
Mr Mason was one about 400 volunteers around New Zealand who measured weather data daily, adding to a database climate scientists used in their research.
