Easement
An easement is a written agreement under which one party receives a right and benefit from another. In the case of a transmission line easement, it conveys the right of Transpower to construct, operate, maintain and upgrade a transmission line over a strip of land, which is defined in an easement transfer. The landowner retains the right to use the easement land subject to some restrictions related to operation of the transmission line.
Electric fields
Electric fields can occur naturally or be man made. Electric fields are produced by the voltage on a wire. The higher the voltage, the stronger the electric field. The strength of an electric field is measured in thousands of volts per metre (kV/m). Electric fields are strongest close to their source and drop off quickly as we move away from the source. All Transpower's new  lines are designed and operated so that they comply with the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines for electric and magnetic fields.
Electricity Authority
The body set up to oversee and administer the Electricity Industry Participation Code.
Electricity Commission
Between 2003 and 2010 the government appointed body with responsibility for managing rules and regulations governing the operation of the electricity sector. From 1 November 2010, governance of the industry passes to the Commerce Commission and the Electricity Authority.
EMF
With regard to transmission lines EMFs are strongest close to the wires and become weaker further away from the wires. Electric and magnetic fields (EMFs) are present wherever there is electricity – including in the home, office and worksite.
