Figure 6.
The stream order map covers the Auckland region from approximately 35 degrees 50 minutes south to 37 degrees 30 minutes south and 173 degrees 50 minutes east to 175 degrees 50 minutes east. The legend classifies streams as first-order, second-order, third-order, and fourth-order, with other values also indicated. First-order and second-order streams form dense branching networks throughout the mainland and surrounding islands. Third-order streams follow several larger drainage routes, while fourth-order streams occur along a few major channels in the northern, western, and southern parts of the region. A compass indicates north, east, south, and west. The scale bar extends from 0 to 100 kilometres, with marks at 12.5, 25, 50, 75, and 100 kilometres.Stream order map
