A launch blown onto rocks by the Trinity Wharf hotel overnight is one of the few visible signs of a storm that appears to have mostly passed Tauranga by.

Wind speeds across the harbour peaked about midnight at 35-40 knots (64-74 km/h), says Port of Tauranga operations manager Phil Julian.

A boat has hit the rocks at Dive Crescent.

The easterly wind across the harbour has dropped to 20-25 knots (37-41 km/h) today, but outside the harbour entrance at A beacon, the easterly is continuing at 35-40 knots and pushing a five metre swell, says Phil.

Salvors were this morning going to check the hull of the launch for damage before towing her across to the marina travelift.

The launch is believed to be Adi Kuila, a displacement hulled game fishing boat built in kauri.

While firefighters further north had a busy night clearing roads and securing roofs, Tauranga fire fighters had no emergency calls.

Katikati volunteers were called at 4.40am to power lines arcing.

Te Aroha firefighters were called out 24 times overnight, mostly to wind related events; trees and roofs, with some flooding, says Northern Fire Communications centre shift manager Colin Underdown.

'They were just in the right place for the way that wind came across,” says Colin.

Thames District Council is also reporting overnight calls were less than expected with only power outages and some debris called in.

Kauaeranga Valley Road was blocked near the Christian camp by a fallen pine tree around 5:30am and fire services report that a power line had also come down. Contractors are removing the tree. Residents there should expect some delays coming into town this morning.

The Coromandel's Facebook community has reported intermittent power outages in Whitianga, Komata, Omahu, Paeroa, Wharepoa, Thames, Coromandel town, Waikawau, Tapu-Coroglen Road, Thornton Bay and Waiomu.

PowerCo says it expects faults around the Thames and Kopu areas to be fixed in the next hour and the rest by about 10am.

Meanwhile the Metservice has issued a severe weather warning at 8.36am for Northland, Auckland, Coromandel Peninsula.

In Northland, Auckland and the Coromandel Peninsula, including Great Barrier Island, severe easterly gales with gusts of 130 km/h in exposed places are expected to continue today, but should start to ease in Northland this evening and about Auckland, Coromandel Peninsula and Great Barrier Island tonight, with the wind flow turning more to the northeast.

Winds of this strength have the potential to damage trees, powerlines and unsecured structures and make driving conditions hazardous.

Although further rain with localised heavy falls can be expected in Northland during today, widespread heavy rain has eased and the heavy rain warning for the region is lifted.
