What people don't realise is that even with our New Zealand super fund, which presently is over $50 billion—probably closer to $60 billion—that doesn't get used to help minimise the cost of New Zealand super, it doesn't kick in, until about 2033 or 2034. Even when we start to apply that fund—which possibly might be worth $100 billion at that stage—even starting to use it to top up the superannuation payment will only account for about 6 or 7 percent of the total cost of New Zealand super at that point in time. So New Zealand super is just an escalating wave that gets bigger and bigger, like a tidal wave, in terms of cost for the Government. As I've said before, in a generic sense, it doubles in terms of the cost of GDP of New Zealand from 4.8 to just over 8 percent.
