  • About Us

  • Our Company
  • Based in Blenheim in the sunny Marlborough Region, Wallace Diack Chartered Accountants Ltd is well known for being a forward-thinking accounting and business advisory practice. We have a reputation for quality advice and for being able to think outside the accounting square.

    Our client base covers the range from individuals with rental properties, family trusts and small to medium businesses, professional people, right through to large companies and groups of companies.

    The accounting firm was first established in Blenheim in 1957. Recent years have seen growth of around 80% and Wallace Diack Chartered Accountants Ltd is now one of the largest accounting firms in the Marlborough region.

    That growth along with an 89.2% customer satisfaction rating has been earned through our commitment to strong relationships and through our "professional smarts". But we still see ourselves as a small friendly accounting firm who work well together with our clients' best interests at heart.

    We appreciate that selecting a firm to entrust with your accounting requirements is an important decision, intensified by rapid economic changes, increases in competitive pressures, and resource availability. With our benchmarking, cash flow forecasting, and other tools, Wallace Diack is well placed to help you make an informed decision.

  • Karen Draper, Associate

    EMAIL: Karen@wallacediack.co.nz     MOBILE: 021 130 4032

    Karen re-joined the Wallace Diack team at the beginning of January. She initially took over Pete Ewan’s accounting role and from April 2022 will co-lead the practice with Tony de Reeper.

    Karen says “I’m super excited about the opportunity to work with our staff and clients again.” Everybody who knows Karen recognises her as accomplished, professional, experienced and relentlessly energetic.

    She knows first-hand about running a business and the dedication and commitment involved. Karen is on the board of several community and professional organisations.

    Karen is a Chartered Accountant, gaining her qualification with Tony as her CA mentor. She has a Bachelor of Commerce (Accounting and Finance) degree and a Graduate Diploma in Professional Accounting.

    She has broad accountancy and taxation experience across a range of industries. Karen is a member of the Institute of Directors. Along with her partner, she has also been involved in several business start-ups.

    She first began work with Wallace Diack in 2006. She then headed off on her “big OE” where she worked in Canada and Australia. After returning to Blenheim, she returned to Wallace Diack before the lure of the corporate world drew her away again. Staying close to her roots in Marlborough, she worked in a variety of businesses. There she drove efficiencies and facilitated process improvement within the financial systems. She has core skills in high-level financial management and understanding of business. She combines this with her risk and critical process identification and mitigation.

    Karen will be a perfect fit into the Wallace Diack philosophy. Our goal is always to help our clients use information to drive their performance. I can’t imagine anyone I would rather be selling my Wallace Diack shareholding to.” says Hamish.
