A report with the above title is now being prepared for publication by the Department of Scientific and Industrial Research. The work embodied in the report was carried out by representatives of four divisions of D.S.I.R., who have been collaborating as a Microzoning Committee since 1968. A smaller report on microzoning in the Pauatahanui area was issued in 1970, but the Wellington study is the first in a major urban area to have been undertaken in New Zealand. It is hoped to extend this type of work to other parts of New Zealand as time, permits.
