A study was undertaken to investigate the impact of job characteristics on work attitudes of New Zealand freezing workers, using a modified version of Turner and Lawrence' s ( 1965) Requisite Task Attribute scale to assess levels of job dimensions, and a modified version of Hackman and Oldham's ( 1975) Job Diagnostic Survey to assess affective responses to the job. Questionnaires were administered to 150 male subjects from a variety of o ccupations in two freezing works. Significant main effects on index were found for occupation, tenure, length of work, work's location, area of socialisation, education and age factors. Moderating effects on the task characteristic-affective responses to the job relationships were also investigated. Moderation was found to occur for this relationship for the factors of work's location, length of work, supervision satisfaction, social satisfaction, growth satisfaction, education and growth need strength. The dimensionality of the jobs was investigated and a moderate degree of intercorrelation was found. The Hackman and Oldham ( 1975) model was found to be inadequate in the present context.
