I'm never visiting you in Wellington now ;-) If it's the aluminium you're worried about try Old Spice deodorant. I'ts for men and comes in a stick. I've been using it for years. The only other one that worked was white tea and lavender from the health food shops but it's about $15 so twice as expensive as normal deodorant. Great story, I didn't know about the mosquito's either. They bite me all the time, I'm like a magnet for them.
