The Reserve Bank of New Zealand determined that there were sufficient Threepences already in circulation, so there was no need to mint any more for 1949. This is a common practice of many central banking agencies around the world.
There was no New Zealand 1949 Threepence minted.
There were 1,128 New Zealand "Waitangi" 1935 Crowns minted. There were 200,020 New Zealand "Royal Visit" 1949 Crowns minted.
There were only 200,020 New Zealand 1949 Crowns minted and most of the surviving coins are in the hands of collectors. There is no indication that any substantial numbers of them have turned up in Afghanistan.
There were 35,043,0000 New Zealand one cent coins minted for issue in 1974.
All New Zealand predecimal coins were last minted in 1965.

Zero. No general circulation New Zealand decimal coin has any silver content, or any other precious metal. Prior to 1947, New Zealand predecimal silver coins had a 50% silver content. All "silver" coins minted from 1947 onwards were made from a copper-nickel alloy. The only exception to this was the 1949 Crown (Five Shillings) which was minted from 50% silver.
There were no New Zealand Halfcrown coins minted from 1954 to 1960 inclusive.
The smallest mintage of New Zealand predecimal general circulation coins was the 1961 Halfcrown with only 80,000 minted. The smallest mintage of New Zealand decimal general circulation coins was the 1997 Two Dollar coin with only 1,008,000 minted.
