But he said he did not believe the result was a factor in Mr Key's thinking, because some returning Cabinet ministers had much smaller majorities, and he and his electorate campaign team had done well against the party and electorate vote targets they had set themselves.
Ms Lorck received 2329 more votes than 2011 Labour candidate Julia Haydon-Carr, while votes for Mr Foss fell by 841.
However, the number of party votes National received in the electorate increased from 17,935 in 2011 to 18,680.
Mr Foss' assessment appeared to be backed by Mr Key, who told a press conference yesterday following the reshuffle announcement that Mr Foss' demotion did not reflect any poor performance on his part, but was simply about changing the "starting line-up".
Mr Foss said he expected to be kept busy in his new Veterans' Affairs role with next year's commemorations of the centenary of the Anzac landings at Gallipoli.
"I know the RSA boys will be very happy," he said.
"I was talking to them the other day and they said, 'Look, in the reshuffle, if you become Veterans' Affairs Minister that would be fantastic'. Lo and behold, two weeks later I am."
Labour's newly-elected Napier MP, Stuart Nash, said he was sorry to see Mr Foss dropped from cabinet.
"I'm sad that Mr Foss's hard work hasn't been recognised. I hope we can form a cross-party team to advocate for the issues that are important to the people of Hawke's Bay."
