Since Christ isn't mentioned in Vedic scriptures, you will find that Hare Krsna's formulate their views based their own social and religious backgrounds and that those views are quite varied.

Krsna is God - the source of everything and everyone, so obviously Christ is related to Krsna.

Some of the more interesting and thought provoking writings on Christ in relation to Krsna (in my opinion anyway) have been provided by Bhakti Ananda Goswami, a disciple of A.C. Bhaktivedanta Swami's who is also a very devout Catholic. In his writings he has equated Christ with Lord Balarama. This is obviously in consideration of his being called the second person in the triune God as well as being specifically called as the saviour of mankind. His understanding is unique amongst Hare Krsna devotees because he has understood both traditions from within the paradigms of their own theology and seems to have reconciled them in such a way as to keep intact the unique divinity associated with Christ in the Christian tradition.

Most other interpretations of Christ and who he is as presented by Hare Krsna devotees equate him with a good servant and call him a Guru. In other words, most of the time the Hare Krsna's equate him with a perfected jiva and don't see him as a divine incarnation (vishnu tattva). Most Christians find this type of idea to be offensive.
