Waihi and Gold

About Us / Waihi and Gold

Our roots go deep. Few parts of New Zealand can offer so much history - glimpses of the hard-fought, gold-rich, pioneer lifestyle permeate the town. Step back in time, and wander through years past in today’s friendly atmosphere.

Gold Fever

It was the lure of gold that brought people to Waihi in numbers. In 1878 gold-bearing quartz was found on Pukewa spur, a Maori burial ground which soon became the famous Martha Mine. Tents and crude huts were gradually replaced with today’s still visible miners’ cottages.

By 1908, Waihi was the fastest growing town in the Auckland Province with a population three times that of Hamilton. Miners took their families to Hamilton on long weekends to escape the bustle of Waihi. The mighty Martha Mine became one of the most important gold and silver mines in the world. By 1952, when it closed, around 5.6 million ounces (174,160kg) of gold and 38.4 million ounces (1,193,180kg) of silver had been produced from some 12 million tonnes of ore. At today’s bullionprices (April 2000) of NZ$550 per oz for gold and NZ$10 per oz forsilver, that’s a value of $NZ 3.1 billion for gold and $NZ 384 million for silver.

Their claim was taken over by William Nicholl in 1879. He pegged out five acres, named the claim ‘Martha’ after a family member, and later a few small claims amalgamated to form the Martha Company. By 1882 the first battery was in operation.

The First Waihi Gold Mining Compnay

In 1890 the Martha Company and other claims were bought by the Waihi Gold Mining Company of London, who invested a great deal of capital into the mine.

At the time, trials were being carried out to find a more efficient way to extract precious metals from the quartz rock. By 1894, the Forrest / MacArthur process had been developed and the use of cyanide in the gold extraction process was adopted world wide. This process enabled a higher percentage of gold and silver to be extracted from hard rock, making viable many operations that would otherwise have had to close.

The Martha Mine became one of the most important gold and silver mines in the world.

By 1952, when the mighty Martha Mine closed, around 5.6 million ounces (174,160kg) of gold and 38.4 million ounces (1,193,180kg) of silver had been produced from 11,932,000 tonnes of ore.

Seven vertical shafts had been sunk for the underground Martha Mine; the deepest was 600 metres from the surface. Radiating from the shafts was a network of 175 kilometres of tunnels on 15 horizontal levels. A work force averaging 600 men was employed over the seventy year lifespan of the mine. In 1909, when gold production peaked, a total of 1500 people were employed in the mine and at the Victoria Battery.

Explosives were used to loosen the rock. The ore was mined with picks and shovels and loaded into wagons. Miners pulled or pushed the wagons inside the tunnels on carriage rails. Sometimes horses were used to pull the wagons. The ore was weighed and sent to the surface in cages, similar to lifts. Ore was then loaded onto the rake train to be transported to the Victoria Battery at Waikino, where it was crushed and treated to extract the gold and silver.

Groundwater was pumped out of the workings to enable the miners to work in the tunnels. From 1904 to 1913 the dewatering pumps were powered by steam engines that were housed in the Cornish Pumphouse, a landmark that still stands beside the Martha Mine today.

Electricity was introduced in 1913. The first hydro electric powerstation on the Waikato River was built by the Waihi Gold Mining Company at Horahora. This power station was later flooded when Lake Karapiro was formed. Around 7000 litres per minute of tepid water was pumped from underground. It flowed through the deep gutters lining SeddonStreet to the Ohinemuri River and also filled Waihi’s public swimming pool.

The End of the Original Martha Mine

The end of the original Martha Mining did not end in 1952 because the Martha had run out of gold; the current operation is evidence of this. Rather, a series of factors led to a decline in production:

The international gold price was fixed at $US35 an ounce, limiting the revenue the mine could make.

The machinery needed to be updated, although the technology was available to do this, the money was not.

There had been two World Wars and the Depression of the 1930s, depleting manpower and creating a difficult economic climate.

It was not possible, given these factors to profitably mine the lower grade ore.

In the 1970s and early 1980s the gold price increased. Exploration and prospecting work identified the economic resource that is being worked today.


During the period Martha was mined, other claims were also registered. These included the Amaranth, Dulcibel, Rosemont, Union,Winner, Britannia, Old Waihi, Silverton, Nelson & Nut and the Young Colonial. Of those registered claims, only a few produced gold.

Some of the main producers (with their values in pounds) were:Martha Co./ Martha Extended Co. (1882-1886) £17,370. Union Co.(1885-1887) £2,375. Rosemont Co. (1885-1889) £932. Silverton Co.(1886-1889) £48,346. Union Waihi, Rosemont and Silverton Waihi Co’s.(1887-1902) £107,048. Waihi Gold Mining Co. (1887-1954) £28,469,011. Waihi Grand Junction Co. (1897-1939) £2,739,623. Cassels Co. (reclaimed tailings, 1893-1896) £19,285.

From 1882 to 1954 the Waihi area produced a total of £31,403,981 worth of gold. At the Martha Mine, 11,932,000 tonnes of ore was mined, yielding 174 tonnes of gold and 1,193 tonnes of silver. This production of 5.6 million oz of gold and 38.4 million oz of silver, at today’s bullion prices (April 2000) of NZ$550 per oz for gold and NZ$10 per oz for silver, would give a value of $NZ 3,108,000,000 for gold and $NZ384,000,000 for silver.
