British High Commissioner Vicki Treadell says Britain would not abuse diplomatic immunity because it is there for a good reason.
"Our position on this is very clear, that you have it for the purpose of representing Britain and doing your job.
"You don't have it to get away with criminality," she told the Herald.
She would not comment on the current case in New Zealand - which does not involve a British diplomat despite TV3 running a picture of a British flag on Monday during an item on the diplomat who fled New Zealand under diplomatic immunity after being charged with sexual assault.
Mrs Treadell said diplomatic immunity allowed diplomats to go about their business on behalf of their government and was particularly useful in countries with poor human rights.
