The Surveyor-General to the Hon. Minister of Lands. Sir,— Wellington, 30th August, 1921. I have the honour to present herewith the report on survey operations for the year ended 31st March, 1921. In doing so I would draw attention to the fact that the Surveyor-General in charge of these operations until the 25th October, 1920, was Mr. T. N. Brodrick, Under-Secretary for Lands. The following report is therefore partly based upon the work carried out under lii.s guidance. I have, &c, W. T. Neill, Hon. D. H. Guthrie, Minister of Lands. Surveyor-General.
