In New Zealand, over the years the stamps were limited to the pre-payment of postage on correspondence posted by the Government Life Insurance Office for delivery within the country. But, on 27-Mar-1969, this condition was relaxed and the stamps could be used on mail to both inland and overseas addresses.
1969, marked the centenary of the founding of the Government Life Insurance Office and a new series of stamps was issued to mark this occasion. Lighthouses, the symbol of the New Zealand Government Life Insurance Department, were again the subject depicted on the stamps.
Cape Egmont Lighthouse was commemorated in the 1969 series of New Zealand Government Life Insurance Office 4c stamp released on 27-Mar-1969.
The change in the name of the business from "Government Life Insurance Department" to "Government Life Insurance Office" was also marked from the 1969 stamp series.
