During the games Inspector Mark Harrison and Steven Gibson were based at the New Zealand High Commission in London while Inspector Blair Telford was based at the rowing venue at Eton.
Detective Inspector David Long was based at the sailing venue at Weymouth and Detective Inspector Lance Burdett with the New Zealand team at the Olympic Village.
Mr Wildon said the officers provided advice, support and, if would have provided assistance had there been a "consular incident", even though they had no police authority.
He said they flew economy class and their accommodation was a mixture of private and rental.
Mr Burdett remained at the village to stay with the Paralympic team and is due back in New Zealand tomorrow.
