Bubbles are being used this week as a symbol to promote greater understanding of the cystic fibrosis, Cystic Fibrosis Association of New Zealand membership liaison officer Julian Cox said.
"We wanted to raise awareness for cystic fibrosis and this seemed a good way to do it. It's like the Cancer Society with Daffodil Day, only bubbles are cheaper to produce and a bit more fun."
Mr Cox said the secret to the bubble recipe was using a mixture of detergent and lubricant, which gave the bubbles elasticity and meant they could be made much bigger than normal.
Cystic fibrosis, which causes mucus in the body to become thick, blocking ducts and tubes of body organs, is the most common life-threatening, genetic condition affecting New Zealanders. One in every 25 people in New Zealand carries the CF gene.
Volunteers will be out and about collecting donations next weekend.
