Hornworm of a Convolvulus Hawkmoth

Dear Gertie,
This is a Hornworm, the larva of a Hawkmoth in the family Sphingidae.   Its color, markings and the look of its horn lead us to believe this is the larva of a Convolvulus Hawkmoth,
Agrius convolvuli, which is pictured on New Zealand Invertebrates where it states:  “Favoured host plants in NZ are the bindweed and kumara.”  Butterfly House also provides a list of food plants.
