The scale of the emergency response to the grounding of the Rena has been downgraded from a national response, to a regional one.
It means the Bay of Plenty Regional Council will now assume responsibility for ongoing monitoring and future clean-up activity.
National On Scene Commander Rob Service says the transition marks a real milestone, and is testimony to many months of hard work by the oil spill response team.
Maritime New Zealand will continue to have a team in Tauranga overseeing the salvage.
