Interesting recording this well known pest of horticulture, the Codling Moth, on Bursaria spinosa. Assuming it is C. pomonella, it's features are not as distinct as i would expect, but they do correspond,
according to https://en.wikipedia.org/wiki/Codling_moth the adult moth can feed (clearly this article reference artificially raised moths - diluted honey and molasses are not common in the wild) Suggestion based on dark colour, shininess, body shape and posture.
