A former scientist from AgResearch's now defunct Wallaceville site says the latest round of staffing cuts at the Crown Institute form part of the largest loss of scientific talent in New Zealand since the Second World War. The Crown Research Institute is looking to axe up to twenty percent of its agricultural scientists, following years of it slashing staff numbers. Professor Ken McNatty who is the former leader of the AgResearch Wallaceville reproduction group, says it's a national tragedy.
