Civil Defence emergency operation centres were opened in Wellington, Porirua and Lower Hutt late in the evening of June 20 as the southerly storm got progressively worse. Emergency services and council contractors were kept busy dealing with fallen trees, damage caused to buildings, including roofs being blown off and windows blown in, and other wind-related problems. Properties on Wellington's south coast were worst hit, with residents in Kingston, Melrose, Island Bay and Lyall Bay particularly affected.

Power was out to more than 30,000 homes across the Wellington region. Areas affected included Trentham, Titahi Bay, Wingate, Wainuiomata, Miramar, Kingsley Heights, Makara, Ohariu Valley, Belmont, Seaview, Petone, Newlands, Tawa, Plimmerton, Mana, Gracefield, Waterloo, Korokoro, Days Bay, Naenae and Porirua. Two days later, 1200 homes in the Wellington region were still without power.

Air New Zealand suspended all flights into and out of Wellington Airport from the evening of June 20 and morning of June 21 because of the high winds. Region-wide power outages and the threat of trees falling on rail lines had also forced all Tranz Metro train services across the region to be cancelled for the night. The Cook Strait ferries were also cancelled.

Fallen trees and debris partially blocked the northbound and south bound lanes of State Highway 2 between Ngauranga and Petone. High winds also sent waves crashing up onto the southbound motorway. The Police advised people to only travel if it was absolutely necessary.

Many smaller roads were also closed by slips, fallen trees and other debris; these included Paekakariki Hill Road, both roads to Makara Village and Makara Beach and Middleton Road, between Johnsonville and Churton Park.

The highest gust, of 200km/h, was recorded at Mount Kaukau. About 140km/h recorded in Kelburn and Wellington Airport.

All school bus routes were cancelled on 21 June. Commuter buses did not travel into Eastbourne or Wellington's south coast and, with Wellington's trolley bus network hit by power cuts, there were serious delays.

Some schools in the region were closed on 21 June, as were all kindergartens in Wellington City and some in Hutt City.

More than 500 trees were reported down within Wellington City. The worst affected areas were Johnsonville, Tawa, and Mt Victoria, where there was extensive damage to the town belt.

The Hutt Hospital treated 5 people at its emergency department for minor injuries sustained when they were knocked over in the wind on 20 June. Power was out to two administration buildings at Hutt Hospital on 21 June, but medical services were not affected.

12 houses at Stanmore Bay were damaged during the storm.
