Babywearing in the 1970s - New Zealand

I came across a vintage baby carrier on ebay called the Maral which led me to discover an interesting bit of babywearing history.  This carrier was patented in the 1969 in New Zealand and was part of a revival of interest in babywearing that occured in the late 1960's. Baby carriers were especially popular among Le Leche League members. 

Marilyn Campbell in 1969 ran Maral with her husband Alistair and also organised the first formal La Leche League meeting in upper Hutt. 

Diane Hildreth "Yes Maral. When I was with Parents Centre Upper Hutt we promoted them in our magazines. I had one for my son Iain when he was a baby. They were fantastic. You could wear them back and front, adjust the straps and they provided head support which others on the market did not. I could do the veges for tea, vacuum, do the washing, all while I had in safely close to me."

Christine Oliver "All of my 4 babies were carried in a bright yellow one of these in the 1980s. I offered to sell them in Perth WA as I had so many queries about where to purchase but Marilyn was content to keep the business small and local."

Do you have any memories of the Maral baby carriers or of babywearing in the 1960's or 1970's in New Zealand?
