But Cassidy told the board that in light of feedback from numerous people, the advert would be cut partly to keep Weepu and his family out of the limelight and because of concern that it could "cut across" another government-funded message.
The Health Ministry's acting deputy director-general, Dr Ashley Bloomfield, confirmed the ministry had initially approved the advert, "because of its appropriateness in terms of delivering a smokefree message".
But he said the council was able to make its own decisions.
"We supported the HSC seeking feedback from groups such as Plunket and La Leche League. When these organisations raised concerns, there was further discussion within the ministry and we concurred with the HSC's decision to remove the clip to ensure consistency with overall public health messages."
Responding to Robertson's letter, La Leche League chief executive Alison Stanton said the advert showed those behind the funding and making the commercial "do not understand the issues around promoting, protecting and supporting breast-feeding".
She said it was widely recognised that images of bottle-feeding "strongly negate" messages promoting breast-feeding.
In the days following the initial contact, the council received 67 emails asking for the shot to be removed.
In other emails, council chief executive Iain Potter told senior Health Ministry staff there had been a "hysterical response from some La Leche members".
This meant "all and sundry across the health sector" became involved and only served to slow what had been a "considered and rational consideration of options".
After the Herald on Sunday revealed the axing of the bottle clip, another 60 protested at the removal.
