"NIWA did everything they possibly could to help us, except hand over the adjustments. It has turned out that there was actually nothing more they could have done -- because they never had the adjustments.... None of the scientific papers that NIWA cited in their impressive-sounding press releases contained the actual adjustments....The main objective of our temperature study was not to show that the raw data has been tampered with, even though that opinion was emphasised and cannot yet be excluded. Our objective was achieved upon Tim Mahood’s admission on 29 January that 'NIWA does not hold copies of the original worksheets.'"  Richard Treadgold recalls the history of the challenge to NIWA about how it adjusted past temperature records.
