He wanted to work with absentee landlords to improve the look of the main street.
"This is the gateway to the Wairarapa - we should set a standard.
"We want people to say: wow, if the rest of the Wairarapa is like this ..."
Mr Montgomerie said it was a good result, after campaigning with fliers, meeting lots of people and "getting my name out there".
"My message was for a bit of change for council, I think the council needs to focus more on how it attracts young families to Wairarapa.
"With population projections, by 2031, medium age [here] will be 50, and one in three will be over 65.
"We really have to see what we can do, to make sure there are sufficient people of working age, but also meeting the needs of people at that point."
He also wanted to address management of council assets, citing the empty library in Greytown.
"Obviously the challenge now is to get some of these things happening."
He said he would celebrate over dinner on Saturday night.
