51. Powers of entry for survey and investigation purposes---(1) Where
 an electricity company wishes to undertake a survey or other
 investigation on any land for the purpose of gathering information
 necessary for any application for any right, consent, or permit, or for
 the preparation of any report, required for any proposed development,
 the electricity company may, upon giving the owner and occupier of the
 land not less than 10 working days' notice of its intention to do so,
 apply to the District Court for an order under this section.

   (2) On being satisfied that the proposed survey or investigation is
 necessary for the purposes of the proposed development, that the
 proposed development may properly be undertaken by the electricity
 company, and that the electricity company has taken all reasonable steps
 to negotiate an agreement for entry, the Court may make an order
 authorising the electricity company to---
   (a) Enter and re-enter the land at reasonable times, with or without
         such assistants, aircraft, boats, vehicles, appliances,
         machinery, and equipment as are reasonably necessary for making
         any kind of survey or investigation:
   (b) Dig and bore into the land and remove samples of it.

   (3) Every order made under this section shall specify---
   (a) How and when entry is to be made; and
   (b) The specific powers intended to be exercised; and
   (c) Such other conditions as the Court thinks fit to impose.

   (4) Before exercising any powers authorised by an order made under
 this section, the electricity company shall serve the order on the owner
 and occupier of the land to which the order relates.

   (5) Every officer, employee, or agent of the electricity company
 acting pursuant to an order made under this section shall have with him
 or her and shall produce on initial entry and if required to do so,
 evidence of his or her authority and identity.
