From this entry, not from the index: Frequently confused with Australia's flag, the two sharing a Union Jack canton and Southern Cross motif, distinguished by New Zealand's four (rather than six) constellation stars and the absence of a Commonwealth Star.

Computed at build time: each flag is rasterised to 64x48, and the score is 0.55 × colour overlap + 0.45 × structure. A different weighting would rank these differently. How the index works.
