After a few days feeling ill, she saw a doctor. "I just felt sore ... funny aches and pains, but I didn't think it was anything major.
"I was diagnosed with acute leukaemia. I was really sick and I ended up on life support for weeks. I pretty much almost died."
The couple had moved to Australia in 2009 hoping to live and work there for a year before moving back to New Zealand, where they have lived for the past 13 years.
She was admitted to the Royal Melbourne Hospital and started chemotherapy treatment.
The family decided to move back to Auckland later that year when things began looking up for Mrs Hounsell.
"Unfortunately I relapsed in November last year. I had a bone marrow transplant this Easter. But again, the leukaemia came back.
"At the moment it's gone and I'm just about to start chemotherapy in the next few weeks and get ready for another bone marrow transplant from my brother."
She has learned to accept that she has leukaemia, but said there were tough days.
"I have a 5-year-old little girl. When I went into hospital last time, she asked: 'Are you dying, Mummy?'
"I was quite upset, I didn't want a little girl to be having thoughts like that."
The Hounsell family are among thousands of Kiwi families who get support and financial help from the Leukaemia & Blood Foundation.
About 2200 New Zealanders are diagnosed with a blood cancer each year. It is the fifth most common cancer in the country.
Executive director Pru Etcheverry said with so many people affected by a blood cancer in New Zealand, it was important to educate and raise awareness.
"I don't think most people know just how common it is. Six New Zealanders are diagnosed with a blood cancer - leukaemia, lymphoma and myeloma - every day. So we very much value any opportunity to raise awareness," Ms Etcheverry said.
"People can visit our website to learn a little more about the people affected as well as their families because ... it's just as difficult for their families."
