When the third series aired in New Zealand on TV One, it has managed to out-rate "24" (2001) from the rival channel, TV3, as both shows competed on the same time slot. Some episodes out-rated "24" (2001) by 4-1.

On 12 May 2006, ITV announced that the third series was the last, due to savings. Two stories were in preparation for shooting in Portugal when the ITV Network Centre decided to cancel plans for a fourth series. Carnival hopes that the show might someday be picked up again by another channel.
