Section I: Core Identity Fraud Analysis

The Jenssen/Janssen Distinction

Research Date: 2 January 2026 Classification: Forensic Genealogical Analysis

Executive Summary

This investigation establishes a critical linguistic and genealogical distinction between two patronymic surnames that appear superficially similar but represent entirely different ethnic origins and family lineages. The confusion between "Jenssen" (Norwegian) and "Janssen" (Dutch) has significant implications for understanding the network structures identified in the broader investigation.

Linguistic Analysis

Patronymic Origins

The surnames in question derive from different Scandinavian and Germanic naming traditions:

| Spelling | Origin | Meaning | Root Name |

|----------|--------|---------|-----------|

| JENSSEN | Norwegian | "Son of Jens" | Jens (Scandinavian form of John) | | JANSSEN | Dutch/Flemish | "Son of Jan" | Jan (Dutch form of John) |

While both names ultimately derive from the Hebrew "Yohanan" (John), they represent distinct cultural lineages. The Norwegian "Jenssen" follows Scandinavian patronymic conventions, while the Dutch "Janssen" reflects Low Countries naming traditions. Any document or record that swaps the "a" for "e" (or vice versa) would effectively be claiming a different ancestral lineage.

The Jenssen Fishing Family of Napier

Company Network Analysis

A comprehensive search of the New Zealand Companies Office revealed 48 results for individuals with the surname "JENSSEN" - all consistently using the Norwegian spelling. The family operates an extensive fishing business network centered in Napier, Hawke's Bay.

The registration of Jenssen Fish Supply at the Oldershaw & Co address establishes a direct administrative connection between the Jenssen fishing family and the Oldershaw accountancy network identified in other sections of this investigation.

Area 2 Inshore Finfish Management Company

Critical Finding: Quota Management Access

Richard Jens JENSSEN served as a director of Area 2 Inshore Finfish Management Company Limited, placing a member of the Jenssen fishing family at the board level of fisheries quota management for the East Coast North Island region.

Shareholding Structure

The company represented a consortium of major fishing interests including:

  • Ngāi Tahu Seafood Resources Limited
  • Sealord Group Limited
  • Talley's Group Management Limited
  • Sanford Limited
  • Te Ohu Kai Moana Trustee Limited
  • Aotearoa Fisheries Limited
  • Various Iwi Fisheries Companies

This places the Jenssen family within the governance structure of New Zealand's Quota Management System, which controls access to commercial fishing rights.

Janssen-Cilag: The Dutch Pharmaceutical Connection

Company Profile

| Field | Value |

|-------|-------|

| Company Number | 2147016 |

| NZBN | 9429032677270 |

| Status | Registered (Active) |

| Date Registered | 30 June 2008 |

| Business Classification | F372020 Drug wholesaling |

| Ultimate Holding Company | Johnson & Johnson (New Brunswick, NJ, USA) |

| Immediate Parent | Janssen-Cilag Pty Limited (Australia) |

Janssen-Cilag (New Zealand) Limited is a wholly-owned subsidiary of the global pharmaceutical giant Johnson & Johnson, with no connection to the Norwegian Jenssen fishing family of Napier.

Genealogical Distinction Summary

The investigation confirms that "Jenssen" and "Janssen" represent:

  • Different linguistic origins (Norwegian vs. Dutch)
  • Different family lineages (Napier fishing family vs. Belgian pharmaceutical dynasty)
  • Different industries (commercial fishing vs. pharmaceutical manufacturing)
  • Different geographic centers (Hawke's Bay, NZ vs. Beerse, Belgium)

Any conflation of these two names in official documents, corporate records, or investigative materials would constitute either an error or a deliberate obfuscation of identity.

Network Connections Established

The Jenssen fishing family connects to the broader network through:

  • Oldershaw Accountants - Registered address for Jenssen Fish Supply
  • Area 2 Inshore Finfish Management - Richard Jens Jenssen was director
  • Fisheries Quota Management System - Access to quota holder network
  • Ahuriri Geographic Hub - All entities centered in Napier/Ahuriri region

Conclusions

This analysis establishes with documentary certainty that the Norwegian "Jenssen" and Dutch "Janssen" surnames represent distinct lineages. The Jenssen fishing family of Napier operates within a network that includes Oldershaw Accountants and fisheries quota management structures, while Janssen-Cilag represents an unrelated pharmaceutical entity owned by Johnson & Johnson.

Any investigation that conflates these two names risks fundamental errors in attribution and network mapping. The consistent Norwegian spelling across all 48 Jenssen family company records demonstrates this is not a matter of variant spellings but of distinct ethnic and family identities.
