The Southland Electric-power Board is now developing Lake 

 Monowai to 5,000 h.p. The works are in hand, and are expected to 

 be in operation within two years. The power-station site is accessible 

 from Invercargill by motor-car about sixty miles. 



In the North Island the Horahora Rapids plant was constructed 

 by the Waihi Gold-mining Company about 1910, and purchased by 

 the Government in 1919. It has a capacity of 8,400 h.p., but is being 

 extended to 10,000 h.p. The power-house is accessible by motor-car 

 from Hamilton (thirty miles) or Putaruru (twenty miles). 



The Waikaremoana installation has just been completed with 

 1,000 h.p. capacity as a first instalment of the large 40,000 h.p. plant. 

 This 1,000 h.p. is employed only to supply Wairoa district a distance 

 of forty miles. It is accessible by coach or motor-car from Wairoa, 

 Hawke's Bay. 



For the Wellington District the Mangahao River power-station 

 24,000 h.p. is in hand, near Shannon, and sixty-five miles from 

 Wellington. The works are in an interesting stage, and are accessible 

 from Wellington by motor-car (seventy miles) or from Shannon (ten 

 miles) . 



Preliminary work is in hand at the Arapuni Gorge, on the Waikato 

 River, for a development of 36,000 h.p. to 96,000 h.p., capable of 

 extension to 144,000 h.p. This is a very interesting development 

 owing to the method of utilization of the natural features of the 

 ground. It is accessible by motor-car from Hamilton, via Horahora 

 Rapids (about forty miles), or from Putaruru (about nine miles). 



In addition, the New Plymouth Borough has a hydro-electric- 

 power plant of about 2,000 h.p. on the Waiwakaiho River, about 

 four miles by road from New Plymouth. Plans have been drawn up 

 for extending the plant to 6,000 h.p. 



Other interesting water-power developments are those of the 

 Dominion Cement Company at \Vairua Falls (2,600 h.p.), twenty miles 

 by road from Whangarei ; Hawera Electric Supply Company, in the 

 Waingongoro River (800 h.p.), about twelve miles from Hawera ; 

 Government Tourist Department at Okere Falls (300 h.p.), about 

 thirteen miles by road or lake from Rotorua ; and the Tauranga 

 Borough plant at Omanawa Falls (1,000 h.p.), about fifteen miles by 

 road from Tauranga. 



There are in New Zealand in all sixty-one electric-power stations,, 

 of a total capacity of 69,000 h.p., made up as follows : Water-power 

 27 stations, 33,500 h.p. ; steam-power 10 stations, 29,970 h.p. ; 

 gas-power 22 stations, 4,460 h.p. ; oil-power 2 stations, 1,070 h.p. 

 The largest of the steam stations are the Auckland City power-station 

 at King's Wharf (13,200 h.p.), and the Auckland Tramway power- 

 station at Hobson Street (8,500 h.p.) ; the Wellington City power- 

 station at Harris Street (5,000 h.p.), and the Wellington Tramway 

 power-station at Jervois Quay (5,300 h.p.). The Wellington City 

 Council is building a large station at Evans Bay (15,000 h.p.) designed 

 to take over the load of both of these city plants, and this station is 

 now in an interesting stage for inspection. It is easily accessible by 

 tram-car (Miramax or Seatoun cars).
