Here is an article from the NZ Herald on Monday 22nd June 1959:
600 TV Sets Already Sold in City
About 600 people have brought television receivers in the greater Auckland since they were put on sale in shops on March 12. But since the Government introduced tariff control on the picture tubes on February 9, the most any firm has been able to import is 100 tubes.
Now the demand for sets is considerably in excess of the supply.
"We cannot keep up with it" said one of the large manufactures. "Right now, it will take 12 months from the time of the order for a set to be delivered."
"If we could get the go ahead from the Government we could have things rolling again in three weeks. There need be no lack of entertainment either.
"People are buying sets now to see Channel Two, 1YA, once a week and Channel Six, transmitted by the Bell Radio-Television Corporation, three times a week.
Their programmes are experimental, but they are a novelty.
"Furthermore 1YA could put on a programme every day right now. It has two studio cameras. a film transmitter with a vast store of National Film Unit material and a pretty good announcer. The whole industry is ready to go."
About 200 retail shops are selling television sets in greater Auckland. The post office is keeping a record of sales so that, when the comes it can call for licences, which are not yet required.
After they went sale, prices of 17-inch sets rose from 135 pounds to 151 pounds and 21-inch sets from 185 pounds to 208 pounds. This retailers said, was because every set sold required at least one call back. With only short terms of transmission on four nights, it was difficult to adjust sets and serials and teach customers how to 'drive' the receivers. Usually a customer had to be visited three times after he bought a set. The original cost estimate has to be raised.
