This and Sunday's photo were taken at dusk.
By the way, I just heard on the radio that 40 years ago today, New Zealand currency became decimal. This means New Zealand got rid of Pound Sterling and introduced New Zealand Dollars. They started studying this in 1959, and decided in 1963, so they weren't in a hurry, were thy? Here's more information.
As well, JB said the first currencies were hidious looking, so I went looking for images. There are not great photos, but here are some I found: currency conversion poster, selection of proposed designs, and some more blurbs. Here's a short clip from what I'd imagine was a TV ad. And I heard a hilarious song by a Derek somebody about the conversion, but I haven't found a clip to that, yet. Here's a link to an afternoon programme on National Radio this afternoon; just the very first part talks about the decimal conversion, followed by an interview with a 91-year old original sheep sheering competition winner. I think the song was played before this segment started.
