39Erecting boundary markers

39 Erecting boundary markers (1) The relevant person must erect a boundary marker at each corner of the survey area and in the angle of at least 2 trenches: (a) that clearly indicate the direction of the boundary of the survey area; and (b) each of which must be at least 1 m in length and 150 mm in width and depth. (2) However, if it is impracticable to cut trenches because of the nature of the ground, the relevant person must place a row of stones, at least 1 m in length and 150 mm in width and height, to indicate the boundary. (3) In addition, if it is impracticable to erect a boundary marker at an actual corner of the survey area (for example, because of the presence of water), the relevant person must: (a) instead, erect the boundary marker on the boundary line as near as possible to the corner; and (b) mark the boundary marker with: (i) the letters "W.P." (denoting "Witness Post"); and (ii) the distance in metres to the corner; and (iii) the direction to the corner. (4) If the relevant person is surveying a survey area that has the same boundary corner as a related area of land, the relevant person may erect only one boundary marker at the corner. (5) For subregulation (4), a related area of land is land for which the relevant person: (a) has made, or is making, an application for the grant of a mineral title; or (b) holds a mineral title; or Mineral Titles Regulations 2011 22 (c) holds an access authority.
