Effective communication with deaf people: A guide to working with New Zealand Sign Language interpreters

When do I need to book a sign language interpreter?

This section advises when you need to book a sign language interpreter.


  • Sign language interpreters are usually needed when communicating with deaf people.
  • Always check with the deaf person involved with the meeting/event before booking sign language interpreters.

Assume interpreters will always be needed (but always check first)

Interpreters should be booked for a meeting or event where deaf people will be present. This will go a long way to ensuring effective communication happens.

Even if you consider that the deaf person can use English fluently, there are reasons why an interpreter may be requested.You should not rely on using written English as a substitute, due to low literacy levels generally in the deaf population.

A deaf person who is proficient in English in everyday use (reading, writing and speaking clearly) may still prefer to use a sign language interpreter for more complex or technical subjects, or in situations where they do not know the person they will be meeting.

Also, lip-reading is not a reliable means of following a conversation. Many sounds of English are not visible on the lips or are indistinguishable from the lip movement alone. Lip-reading is more difficult when the speaker is not familiar to the deaf person.

Always check with the deaf person if they have any particular requirements and preferences before you book an interpreter.

Sign language interpreters and booking agencies may request information about a deaf person to judge the interpreter's competency to interpret for a particular client and in a particular situation.

You can ask Deaf Aotearoa for advice if you are unsure of what to do.

Before a meeting and on request

Book a sign language interpreter if the deaf person, a family member or a deaf representative (such as a support person, advocate, deaf mental health worker or an employment consultant or community relations officer) makes a request for one to be present.

During or after a face-to-face meeting

If you have concerns or difficulties in communicating with a deaf person during a meeting, especially if it is the first time you have met them, ask the deaf person if they would like a sign language interpreter booked for any further meetings.
