Rostami speaks from experience - a childhood bout of polio left him with limited use of his legs and he swims using only his arms. He admits a couple of close calls with the water in his adopted country prompted him to learn to swim - and added fire to his fundraising attempts.
"I chose SLNZ as I know what a fantastic job they're doing. Every time I swim in the ocean I'm very aware of their presence. I'm also aware that funding is limited for their organisation. I feel it's every New Zealander's right to swim safely on their shores and SLNZ enable this to happen."
Aucklander Martin Howard agrees. Every Tuesday for 18 weeks over summer, Howard will drive his daughter, Lucy, from the family home in Epsom to Takapuna beach to participate in the Harcourts Cooper & Co Beach Series.
"For our family, summer means holidays at the beach. While our kids have benefited from years of swimming lessons in a pool, there are subtle differences when you find yourself in an unpredictable, ocean environment," says Howard.
"The Beach Series is a fun and family-friendly way for kids to gain confidence in the ocean, which is why I'm more than happy to make the trek over the Harbour Bridge so my daughter can take part."
