With just a handful of votes left to be counted
last night, Mrs Barlow was already more than 600 votes ahead of her nearest and only rival, sitting councillor Graeme Page.
Progressive results showed Mrs Barlow had 1202 votes, while Mr Page had 582.
In 2010, Mrs Barlow (50) had just a 29-vote margin over Mr Page, and she said the result this time was a ''much more convincing'' win and a big vote of confidence.
''I am really quite humbled and really stoked ... it's a comfortable win this time, not like last time.
''We will have one or two new faces around the council, but it's business as usual. Obviously, people are happy with the job we are doing.''
Earlier this year, the Mackenzie District Council agreed to put aside $160,000 plus contingencies (about $200,000 in total) to prepare a subdivision consent to start a ''self-funding'' redevelopment of 1.2ha of land at Lake Tekapo, which stands to boost council coffers by $1 million.
Mrs Barlow said although those plans were still developing, she was ''thrilled'' she could see them come to fruition.
''I'm thrilled that I have another three years to see something happen.''
