The sheet index diagrams show you the boundaries and names for each of the 451 Topo50 A1 portrait sheets, including the 6 Chatham Islands sheets.
Sheet index diagrams
Where a printed sheet covers a small land area, one-third of the map area overlaps with the adjacent sheet. Sheets that overlap another sheet are shown with a dashed outline.
Topo50 sheet index diagrams and combined Topo50 and 260 sheet index diagrams showing Topo50 and 260 sheet lines are available for both the North and South Island.
