Ms Rangi Parata

Practice Manager

Tui Park Legal

Subject: Application for Office and Client Administrator

Dear Ms Parata,

Kauri Accounting Partners kept 3,000 client files in paper cabinets until I scanned and renamed each one into a shared SharePoint folder, and the team now saves about an hour of searching a day. That project is why the Office and Client Administrator role at Tui Park Legal caught my eye.

Most of my week matches your advert. I keep the Outlook diary for four accountants, booking around 40 client meetings a week, and raise about 120 client invoices a month in Xero, following up late payments with a polite reminder routine. I answer the shared phone and email inbox, replying to routine questions within two hours. At Harbour Dental I ran a list of up to 35 appointments a day and once covered the front desk alone for a full week without a missed booking.

Tui Park Legal's move to a document system is the part of the job I want most, because I have done that move once and know where it slips: names nobody can guess, and folders that drift a week later. Keeping client records accurate and easy to find starts with one naming rule a lawyer can follow without asking. I also check the monthly pack against Xero before it reaches the partners, and that habit of checking before anything goes out matters even more with private legal files.

Bringing the naming rule and a page of my reminder routine to an interview is easy, and any weekday afternoon suits me. Should the file move start in my first month, or after the diaries settle?

Kind regards,

Daniel Osei

Paragraph by paragraph

  1. The opening

    Starts: “Kauri Accounting Partners kept 3,000 client files…”

    Starts with a finished project and its time saving, which tells the reader the writer completes what they start.

  2. Your strongest evidence

    Starts: “Most of my week matches your advert.…”

    Covers the diary, invoices and inbox lines from the advert with a number for each, and adds one example of steady work under pressure.

  3. Why this employer

    Starts: “Tui Park Legal's move to a document…”

    Ties the reason for applying to the firm's own project and answers the records line in the advert with a method, not a claim.

  4. The close

    Starts: “Bringing the naming rule and a page…”

    Offers real working documents and availability, then asks a question that shows the writer is planning the first month.

Why this letter works

  • The opening project is the same change the firm is about to make.
  • Every routine in the second paragraph carries a number.
  • The writer explains where a filing move usually goes wrong, which shows real experience.
  • Accuracy is shown as a checking habit rather than claimed as a trait.
  • The final question invites the manager to picture the writer already in the job.

How to write your own administrative assistant cover letter

  1. If the employer is about to make a change you have already made, open with yours.
  2. Say what usually goes wrong in a project like theirs and how you avoided it.
  3. Show care with private records through a checking habit you already keep.
  4. Mention cover you gave alone, with how long it lasted and what was missed.
  5. Ask about timing in the close, so the reader imagines your first month.

Common questions

How can an administrator from an accounting office apply to a law firm?

Point to the tasks that carry over, such as diaries, invoicing and client records, and show you understand that legal files are private.

Is it fine to tell a firm where its project might go wrong?

Yes, if you base it on your own experience and keep it short. It shows judgment, as long as it does not sound like criticism.

What can an administrator say about phone and inbox work?

Give a reply time, such as routine questions answered within two hours. It shows reliability better than any adjective.
