Premiums for Medical insurance and "destitution insurance" (pension contributions) are deducted from pay packets. A while back, and on another expat website (link below), I reminisced about the days when we used to receive our pay packets without any deductions at all - but those happy days are far behind us now. Property insurance is not compulsory unless one has a mortgage. We had a big hurricane come through here in 2004, but insurance covering damage from storms is quite expensive. My wife and I have our house insured against fire, but not hurricanes any more.
