As fellow members of the Commonwealth of Nations, they exchange diplomatic relations in governmental level rather than through heads of state.
Thus the countries exchange high commissioners, rather than ambassadors.
The high commission is located in New Delhi, India's capital city.
New Zealand has maintained a resident high commissioner in India since 1970, except for a period from 1982 until 1985.
The high commissioner to India is concurrently accredited to Bangladesh as High Commissioner and Nepal as Ambassador.
