Christina Howe |  Senior Community Advocate

Christina comes to GRG with 7 years experience as a barrister and solicitor practising in criminal, employment, immigration, property, ACC, and family law.  She was a founding member of the Family Court Navigator service with the Ministry of Justice leading projects such as Enduring Powers Of Attorney (EPOA) workshops, Family Court Open Days, and extensive community education.

Christina’s passion lies in all things family law related and she has a real desire to see change in this space. Of top priority for Christina for GRG members is making easy-to-use toolkits for grandparents going through the Family Court and pushing for a national register for EPOA’s and wills.

Christina has been largely raised by her grandparents and credits them for who she is today. Without their love and support, she says she would not be the person she is now.  In her spare time she has volunteered as Trustee for Single Parent Services and Hamilton Multicultural Services Trust and enjoys spending time with her Nan and playing piano.

Karla Macdonald |  Communications and Projects Coordinator

Karla has joined our team after returning to Aotearoa after 19 years living overseas. She is responsible for the coordination of our client and stakeholder communications and a growing and diverse range of projects and events to complement our support services and support available for our grandparent and whanau care clients nationwide. Karla is passionate about life, work and helping others - and comes from a background of mining, building, healthcare, retail, and hospitality.  Combining her core and life skills Karla has come full circle with where she started to where she is today.  She is proud of her roots, with her upbringing in the Waikato – where she started voluntary roles in her community at a young age and right through her schooling years.  A highlight for Karla was fulfilling homecare duties as a health care assistant (before, after school and weekends) for her first client at the age of 16.  She furthered her role as a health care assistant until her move to Australia in 1999. Karla is proud to be of Ngāti Māhuta, Ngāti Pou, Ngāti Raukawa.
