The New Zealand government has rules about how to work out the value of things that lose value over time, like machines or buildings. You can find these rules in the Income Tax Act 2007, which is empowered by sections ss EE 27 and EE 28. The rules are about how much value these things lose each year, and they are different for different types of things.

The government has made a table to help you work out how much value things lose. The table has two main parts: one for things that are not buildings, and one for buildings. For things that are not buildings, the table shows two rates: a diminishing value rate and a straight-line rate. These rates are like percentages that show how much value the thing loses each year.

You can use the table to work out how much value a thing loses each year, depending on what type of thing it is and how much it is worth. The rates in the table are different for different types of things, and they help you work out how much value the thing loses over time.
