Part I of the Fisheries Act deals more specifically with the commercial aspects of fishing, and the following regulations set out in detail the controls imposed. The Commercial Fishing Regulations, 1963 deal with the conditions mainly applying to registration and permits. The Fisheries (General) Regulations 1950 include provisions covering net fishing, line fishing, trawling, Danish seining, crayfishing and, in fact, all those matters other than what is dealt with in the special regulations listed below covering separate fisheries. These are the Oyster Fishing Regulations of 1946; the Toheroa Regulations of 1955; and the Whitebait Regulations of 1964. At present seals are totally protected under the Seal Fishing Regulations of 1946, while whaling is covered by the Whaling Industry Act of 1935 and the Whaling Industry Regulations of 1961. Provisions of the Shipping and Seaman Act relating to survey requirements and to the manning scale apply, in particular cases, to fishing boats.
