The wave buoy is back at sea, recording information about wave heights, water temperature and wave frequency.
The buoy, which sits 13km off Pukehina Beach, monitors and records information about wave heights, water temperature and wave frequency.
The live data is shared on the Bay of Plenty Regional Council's website and is especially popular with boaties and surfers in the region.
The buoy has been out of the water since March getting a new computer and other internal upgrades.
Regional council data services manager Glenn Ellery said the necessary parts came all the way from Canada and everything went to plan.
"We have tested that everything is working with the new internals and all the signs are good. While it was out of the water, we gave the hull of the buoy a once-over but it was in good condition for its age and no significant maintenance was needed," Mr Ellery said.
The wave buoy data is back online at the Bay of Plenty Regional Council's live monitoring site.
