This card is chosen because it is also an advert for Sanitarium, and there are not too many issuers who take advantage of doing such a thing. Also the text fits our theme rather well, for here we have "The Bedford Truck used by the Sanitarium Food Company [which] carries more than 13,000 one-kilogram packets of Weet-Bix - or nearly a million individual Weet-Bix biscuits"
The card also has an Auckland address, which is the New Zealand branch of the company, so it is fun to be able to commemorate them too.
You can see the entire set at the Trading Card Database/SBR.
This set is catalogued in our original Australia and New Zealand Index (RB.30), published in 1983, as :
1982-1 Weet-Bix Big Rigs. 76 x 57. Nd. (20) SA2-180
However, immediately below it is what was obviously an allied issue, namely :
1982-2 Weet-Bix Stickers (A). Circular, 73 m/m diameter. Brand issue, 1 known - "I`m Truckin` on Weet-Bix Power" ... SA2-181
So if any reader has one of these stickers do please share as a scan, so that I can add it in.
