While it was hard being away from her two children, initial progress looked positive and had given her a boost.
"The activity of the tumours is showing zero which is very exciting but, just to make sure, I am to go back there in six weeks."
When doctors told the 42-year-old in January that stage-four breast cancer had metastasised to her bones - including hips, legs, knees and crucially her spine - she sought an alternative way to fight the aggressive form of cancer.
First, she had to raise $100,000 to cover costs - a Givealittle account was set up by friends, and people from throughout the world had donated $44,779 to date.
"I am very hopeful, I feel amazing, and I am very very grateful.
"Without all of you raising [money], and Air NZ helping with special fares, it would not have been a possibility at all and my future looked very grim."
Friends worldwide continued to raise money to repay a loan which got her to Germany, and allow to fund follow-up treatment.
"Any donations surplus to my treatment fees I am donating to the Cancer Society, [who are] quietly supporting us all behind the scenes."
