Patterson was also contesting a newly formed Taieri seat this election — an electorate suffering from a congested roster of 11 candidates, including strong contenders in eventual winner, Labour's Ingrid Leary (22,225 votes), and National's Liam Kernaghan, who came second (11,593).
Patterson placed fourth in the electorate, on 1174 votes, behind the Greens' Scott Willis who came third with 1717 votes.
He congratulated Leary, again observing Labour's handling of the Covid-19 crisis had helped her and her party to a landslide victory this year.
"I'm sure Ingrid will make a fine MP for the area."
"There's been a red tide coming in this year, which has blown everyone away, but a tough night for us, obviously.
"It's been pretty humbling."
Patterson, a Lawrence farmer, said he now planned to take time to retrench with wife Jude and his two daughters.
"It's been a massive privilege to have been an MP, and I would have loved to have had a second term, but I'll reassess those options later on."
"It's back to the farm for me, for now."
