You are looking at a schedule called "Old banded rates of depreciation". This is part of the Income Tax Act 2007. It has a table with two columns: diminishing value depreciation rate and straight-line equivalent. The table shows different rates. For example, a 2% diminishing value depreciation rate is equal to a 1.5% straight-line equivalent rate. You can find more information about this in sections like ss DB 46, EC 34, EC 35, EE 30, and EZ 23. These rates help you work out depreciation, which is a way to calculate the value of something over time. The schedule gives you the rates to use for different types of depreciation.
