Ms Latta, who previously worked as a navy medic and has been with WFA for six years, committed to a three-year fundraising effort for the probes, which cost nearly $500 each.
She is through the first hard year, getting a good start with a $10,000 donation from Harbour City Security in Wellington, and raising the rest by putting her cycling skills to use.
Ms Latta is a former professional cyclist and she competed in two 12-hour mountain biking rides in Taupo and Rotorua to get a kickstart on fundraising.
"It's good fun and it's for the cause. There's nothing better to drive you than the fact that you're helping children."
Ms Latta still has to raise another $8000 for maintenance of the existing devices.
"I'll be keeping the spirit alive and finding new ventures for people to donate to."
