1. Inappropriate Spending
This may be the CEO spending up large at Hooters, personal use of taxpayer or ratepayer money, and other spending which is simply not appropriate for a taxpayer funded organisation.
2. Excessive Spending
This is where the spending is on something appropriate such as a Council website, but the amount spent is excessive for the value gained. Just because something is worthwhile, doesn't mean that there should be no reasonable budget for it. For example, spending $300,000 on a website for a district of less than 50,000 residents.
3. Misdirected Spending
This is spending where the policy is misdirected and the spending is inefficient. An example from across the Tasman is Tony Abbott's paid parental leave scheme which rather than cap the subsidy at a level to target low and middle income parents, will provide the greatest subsidies (up to $2,900 a week) to the richest parents - who least need it.
A local example would be the Supergold transport subsidy which has been a financial windfall for transport operators, or interest free-student loans. If the desire is to help low income pensioners with transport costs or to make tertiary education more affordable, there are alternative policies which would achieve these outcomes more efficiently.
