The Cabinet minister won with a 5800 vote majority over Ms Lorck and a total of 16,887 ticks from the 32,457 people who voted on Saturday and the 3602 special votes.
In the 2011 election he won with a 9660 vote majority.
"People judged in their own minds the personalities [of the candidates]," he said.
He said he was tempted to respond and bite back at her brash and bullish game plan.
"It was very tempting to, but I stayed true to who I am and stayed above that. To be fair, her job is marketing and [communications] and she got her presence and her profile out there really well, and good on them, that's probably one of the better campaigns, I'd say, that they've run here for a while.
"That's the bit that takes your energy, just resisting all of that ... you read it, you see it and you hear it and you say 'that's just not right'. You can agree to disagree on [policies] but no one needs that nonsense."
The 51-year-old first contested the Tukituki electorate in 2002, but was beaten by Labour's incumbent, Rick Barker. Mr Foss then won the seat in 2005 and will now hold the electorate for more than a decade.
"They're all different, when we first started out in 2005 we had been working for three years to get to that point and we came from behind [to win]. The people know who I am now and learn more and more about me."
Results from polling booths across Tukituki show Mr Foss was again strong in the National strongholds of Havelock North and Central Hawke's Bay while the vote was split throughout much of Hastings, except Camberley.
"I honestly represent all of Hawke's Bay and all of Tukituki, no matter where someone comes from. Interestingly in those booths a lot is disguised because there's about 9000 advanced [votes] so you don't actually know where they're from.
"Our policies, what we are doing, has been strongly endorsed throughout the Bay. I think 51-21 per cent here and in Napier, so that's a pretty resounding message.
"But I suppose a lot of it is consistency, I know it's my slogan but relentlessly, positively backing the Bay, and I do that, I live that."
After Napier MP Chris Tremain decided to hang up his political boots last year, Prime Minister John Key acknowledged holding the Art Deco City and its rural areas would be a challenge.
"We ticked almost every box across the country bar that one, the vote splitting up there was pretty devastating really, so maybe some people will be looking at themselves in the mirror this morning."
Mr Foss said despite National candidate Wayne Walford losing out, the party vote remained strong in Napier and nearly doubled Labour's.
"That's huge because they're the policies we use to grow the Bay and create jobs. Central Government marrying with local government, that's the key right there," he said.
"I really enjoy being a minister in Cabinet because that means a Hawke's Bay voice at the Cabinet table. That means Hawke's Bay's issues get raised at the highest level.
"When you see stuff take off because of things you've done, maybe in the background, or maybe in Wellington in a policy sense, but which are enablers for the Bay, gee it's satisfying."
Mr Foss thanked all those who voted in his electorate because "they sent a strong statement regardless of who they voted for to those who tried to buy, take, steal our election, our democracy".
"I'm quite humbled, to be honest, after every election that so many people invest their tick in me."
