"They passed within two metres of our bedrooms."
The burglar stole his laptop computer, which was full of information about his candidacy, "ransacked" his office and unbolted the trailer from his blue Subaru - registration CCJ332 - before stealing the car, which had five election billboards in the back.
His wife's wallet was stolen from the house and credit cards have been used in a range of petrol stations overnight, McKeown said.
Ironically, as part of McKeown's election campaign, he pasted a yellow 'open doors' label on to his election billboards, representing his belief that the council needs to maintain transparency.
"Someone has decided to break in through my back door a few days after I put my open doors sign up," he said.
McKeown said he had reported the burglary to police.
This is McKeown's fourth time standing for Auckland City Council. He was first elected in 2001 and has previously served as the chair of Auckland City Council's transport committee.
