No, this road was not named after a pair of Hindu gods, but given the dissension and discord between Maori and Pakeha during the 1860s Land Wars, a force for peace compassion and tolerance would have been welcome.

Rama was born on 9th Day (now celebrated across India as Ram Navmi) in Chaitra Lunar Month in Ayodhya, India when Moon & Jupiter were rising in the east in Cancer sign and four other planets (Sun, Mars, Saturn, Venus) were exalted in their exaltation signs. Pushkar Bhatnagar has been able to establish in his research that the star positions at Rama's birth match the date of "10th Jan 5114BC" around 12:30pm local time; there is no other match for these planetary positions. Prior to the eleventh century there were no temples to Rama, since he was viewed as human.Rama bhakti poetry starts to emerge only in the sixteenth century.

Worship of a deity of Krishna can be traced to as early as 4th century BC.Worship of Krishna as the Supreme Being arose in the Middle Ages in the context of the bhakti movement. From the 10th century AD, Krishna became a favourite subject in performing arts and regional traditions of devotion developed for forms of Krishna.
