Whose Money Are We Guaranteeing?

If the NZ taxpayer is to guarantee the deposits in NZ banks - could someone please first answer these questions: Who is holding these deposits? Whose deposits are being guaranteed? How many depositors are there with $50,000 or more? How many depositors are there with $100,000 or more? With $1 million or more on deposit?
