The MBS Board of Trustees is elected every 3 years.
They take on the governance of the school to create a successful school.


Mark Keenan / Principal


I have been principal at MBS since the beginning of 2015. Prior to this I was a teacher and leader at a number of Auckland schools as well as overseas. I am married to Kate and 2 wonderful daughters Anna and Ruby.

At MBS I want every child to achieve to their potential and be engaged, confident and resilient learners. A key to this is a strong professional development programme for our teachers and developing a meaningful future focused school curriculum. I believe children learn best when there is a strong home/school partnership.

Craig Rooks


During my time on the Maraetai Beach School Board of Trustees since September 2014, I have looked after the Finance Portfolio and am now the current Chairperson.

My wife Nicola and I have three sons, Oliver, Flynn and Rowan, all of which are currently or have attended MBS.  We both have a huge interest in the success of MBS, not only for our own children but for the wider MBS community.  Having primary and now secondary school aged children, we have seen how important it is to support the school and teachers in our children's education by getting involved in their learning.

I believe that every child should have the opportunity to succeed to the best of their ability and that teaching staff need to be supported in the vital job they do in fostering an excellent learning experience.  I have been impressed with the school's commitment to a broad and challenging learning environment and I believe MBS is a great community to be involved in.

I work in the food manufacturing field and am the site manager for Griffins biscuits based in Papakura.  Rugby is a major part of the Rooks household in the winter months and as such I have previously been heavily involved in the local Beachlands Maraetai Rugby Club through coaching, managing teams, club treasurer and for two years as club president.  Being involved in local clubs allows our community to have options available for youth and families so they can experience as much as possible.  As a young parent I was involved in youth mentoring and took an active part in Project K providing mentoring to year 9 students and helping them develop leadership skills.

I have a passion for a rounded, quality education for all children and a desire to support the staff and families of MBS.  I have an enquiring mind and the ability to offer ideas and solutions where necessary, along with an enjoyment of being part of a strong working team.Email:

Wayne Gillard

Staff Representative

I have am privileged to be the Deputy Principal and the Staff Representative on the Board of Trustees at Maraetai Beach School.  I have lived in the community for many years and had a long association with the school. I am passionate about putting students first and providing opportunities for them to be the best they can be. I enjoy coming to school every day and working alongside a talented staff and teaching in classrooms to our vibrant students.

Our school vision is based around three words – People, Potential and Planet. This is always kept at the forefront of decisions and has enabled this school to become the excellent school it is.

We have an amazing environment on our doorstep which we look to use to enhance learning for our students. We have a supportive community who also love to get involved in the wide range of learning experiences offered.

Outside school I always enjoy quality time with my family (I am married with two kids). I am also passionate about sports and run marathons when I can. I am involved in the community with coaching and like to take the opportunity to spend time at our local beaches and parks.

Maraetai Beach School is a great place to be!

Vonja Young

Parent Trustee 

I was co-opted onto the BOT in February 2017 and have been a member ever since.  I hold the Policy and Legislation Portfolio on the current board. 

My husband and I have lived in the area since 2005.  Our son Jack is currently (in 2019) in Year 6 at MBS.  As a family we are passionate about this beautiful community we live in. 

I believe MBS provides our children with wonderful education and wide opportunities.  I love the values our children are taught everyday at MBS. 

I am a Solicitor specialising in family law.  I feel very priviledged to be a parent representative on the BOT at MBS and take my role very seriously.  I am looking forward to the next few years of working with our current board to achieve our strategic goals, always with a focus on growing a community of successful lifelong learners.

María Lamberto Calvo

Parent Trustee

My first contact with Maraetai Beach School was in 2004 when my family moved to this area. I currently have my 3 children at the school and they are loving it. I did my University studies in Spain graduating with a degree in Philosophy and Education and a teaching diploma. I moved to New Zealand in 1997 and started my teaching career in Papakura. I have been actively involved in Education since then and I am passionate about getting the very best out of students. I have been involved in assessment and curriculum development for the last 11 years. I am currently working for NZQA in a variety of roles. I also work as Head of Languages at Kings College.  I currently hold the Property Portfolio for the BOT and working with the Board to bring a great Learning environment for our students.  I aim to continue to use my expertise in Education to help the school continue to lift its profile and to help students get ready to face the challenges they will encounter at secondary school and beyond. I believe the whole community must be part of the education of our youth and parents/whanau and caregivers should be an integral part of this process.

Damian Powley

Parent Trustee

Living in Maraetai for 12 years, raising three children who are all growing up and attending Maraetai  Beach School, I often have to pinch myself for how lucky we are. I think our children have an amazing array of opportunities right on their doorstep, being active members engaged in their community. Maraetai Beach School is a cornerstone in shaping these pathways for stronger, resilient communities.

My background is in project management and strategic delivery. Supporting and ensuring the Board of Trustees continues its great work to maintaining an open and accountable foundation for Maraetai Beach School is foremost in my role as a representative.

Tristan Gilchrist

Board Secretary

My first encounter with the school was over 12 years ago when my son started here because we were looking at moving overseas and this is where his best friend attended.  What started as a short-term option has led to my 4 children attending the school, and me having a job which I absolutely love.  My background is in Human Resources, but I feel so fortunate to have found a role where I am challenged, have diversity in my workday, and am able to build relationships with the students and their families.  I feel so proud to be able to say that I am a part of Maraetai Beach School and look forward to the future with the exciting developments that lie ahead, along with the support of our strong Board, Staff and community behind us.
