Prime Minister John Key thought the candlelight vigil outside his house last night was "not really cricket".

About 30 protesters gathered outside his Auckland home last night in a candlelight vigil commemorating "the numerous deaths of civilians and the illegal killing of 'supposed' terrorists, including New Zealander Daryl Jones -- killed by the US drone strike programme".

Mr Key told Newstalk ZB that he didn't pull a curtain aside to look at the protesters last night.

"I've always been a bit of the view myself that it's not really cricket.


"Yesterday was family day, the afternoon when I got back was Max's birthday, and just generally speaking it's our home environment."

He said he was at a well-publicised National Party conference over the weekend that would have been more suitable to hold a protest at.
