Jane-Marie Alberts, 44, was an "amazing, loving and supportive" mother and partner.
Jane-Marie, who was known as JM, was an account manager at Marac Finance in the Pyne Gould Corporation building in Cambridge Tce.
She is survived by her partner and fiancé of 13 years Derek Neal and sons, Jackson Smith 17, and Sam Neal 10.
Long-term partner, Derek, said JM was "very proud" of her sons and their achievements and "her legacy will continue on through them".
"Our relationship was perfect. We were truly in love and told each other every day. I couldn't have wanted anything more in a wife, to me she was perfect, she had style and impeccable taste, a great personality, gorgeous and athletic," he said.
"From the first moment I met her I thought she was just amazing."
Her "warm smile and infectious laugh" could be heard throughout the office as she chatted to people on the phone, he said.
JM's funeral was held on March 14.
"It was a very, very sad day and there was a huge turn out. It was at one of the biggest funeral chapels in Christchurch but there was only standing room," Derek said.
"It was great for the boys to see how special, well loved and appreciated she was. She was an amazing woman and we all miss her terribly."
