WK Advisors & Accountants

What WK Advisors & Accountants does

WK Advisors & Accountants is a privately held New Zealand chartered accounting and business advisory firm headquartered in Timaru and operating from three South Island offices in Blenheim, Nelson, and Christchurch. The firm traces its origins to the 1987 amalgamation of Winstanley Robbie & King and Kerridge and Sutherland, rebranded to WK in 2015, and has grown through a sequence of mergers including WK Strawbridge (2020), Hargreaves & Felton (2021), and EPA Business (2025). It serves SMB and mid-market clients across the South Island, with particular depth in the wine, viticulture, and agribusiness sectors of Marlborough and Canterbury, offering accounting and tax compliance, financial and strategic advisory, virtual CFO services, tax advisory across corporate, trust, individual, and international matters, and business software implementation.

The firm's service delivery is built on a cloud-based technology stack centred on Xero (Platinum Partner) for core accounting, supplemented by Figured (Platinum Partner) for agribusiness financial planning, Vintrace and Vinsight for winery operations and inventory, iPayroll for payroll, Hubdoc for document capture, vWork for field job scheduling, iCos LIVE for transport management, and Sharesight Pro for investment portfolio tracking. WK differentiates through structured Collaborative Action Programmes (Ignite, Drive, Strive, Thrive), a suite of online business diagnostics covering sale readiness, scale-up, strategy implementation, and culture, and a Mindshop partnership that provides facilitator training and diagnostic content for advisory engagements. Proprietary tooling is light; the differentiation lies in the integration of these third-party platforms with sector-specialist advisor expertise.

Revenue is generated primarily through subscription-style recurring compliance engagements, advisory retainers, virtual CFO fees, specialist tax advisory (including IRD dispute resolution), software implementation professional services, and WKIQ workshop fees. Pricing is not publicly disclosed and engagements are scoped per client. Go-to-market is sales-led and referral-driven, executed through the three physical offices and supported by content marketing, organic social media, community sponsorships, and educational workshops. Customer concentration is moderate, anchored in SMB and mid-market businesses across the South Island with no publicly disclosed large-anchor contracts.
