W made this Official Information request to KiwiRail
This request has an unknown status. We're waiting for W to read recent responses and update the status.
From: W
Dear KiwiRail,
I am requesting the following information regarding all train services scheduled to arrive at Wellington Railway Station between 7:00am and 9:30am, for each of the past five calendar years (2019–2024):
1. On-time performance data
Please provide:
1.1 The total number of scheduled services
1.2 The number and percentage of on-time services
1.3 The number and percentage of delayed services
This should be provided in two formats:
- Daily-level data (i.e. each service per day, with its scheduled and actual arrival time)
- Annual aggregated data (summarised counts and percentages per year)
2. Delay analysis
For all delayed services, please provide:
2.1 A breakdown of the reasons for delays (e.g. mechanical issues, staffing, weather, infrastructure, etc.)
2.2 The count and percentage of each delay reason per year
Acknowledgement that multiple reasons may apply to a single delay
This should also be provided in both:
- Daily-level detail (with delay reasons per service)
- Annual summaries (aggregated counts and percentages)
3. Mitigation and improvement efforts
Please provide:
3.1 Any mitigation plans or operational changes implemented in response to delay trends
3.2 Any evaluations or outcomes of those mitigation efforts
3.3 Any current or planned initiatives aimed at improving on-time performance for these services
4. Raw data request
I request access to the underlying raw data used to generate the above statistics, ideally in a machine-readable format (e.g. CSV, Excel, or similar). This should include:
Service identifiers
Scheduled and actual arrival times
Delay durations
Delay reasons (if applicable)
Date of service
Kind regards,
W
From: W
Dear KiwiRail,
follow up - please provide the aggregated information for on-time services and reasons by year, by train line.
Yours faithfully,
W

Good afternoon
We have received your request dated 25 June 2025, for information on the punctuality of Wellington Bound services, and reasons for any delays over the past five years.
We have transferred your request to Metlink, as part of Greater Wellington, as this information is not held by us and is more closely connected with the functions of Metlink - i.e. they run the services.
In these circumstances, we are required by section 14 of the OIA to transfer your request.
You will hear further from Metlink concerning your request.
Kind regards
Dave

Kia ora,
Thank you for your request for information on all trains scheduled to
arrive at Wellington Station between 7:00am and 9:30am. We are currently
actioning your request for information, and were wondering if you could
please provide some clarification on the below points to assist us with
providing you the most useful information:
1. You specified a date range of 2019 – 2025 for this request, can we
please confirm that you aren’t after any data from this current year
(2025)?
2. Would you like this information to include weekends and public
holidays, or only weekdays?
3. You have specified a time range of 7:00am – 9:30am, are you after
information only in the morning peak or specifically between these
hours?
An initial content search has been carried out with regard to the
information you’ve requested in part 3 of your request (copied below), and
has returned 4240 items. This is being assessed as a minimum of amount of
70 hours of work for officers to assess each item. As such, we have
identified that in order to provide the information requested, it will
unduly impact the organisation’s BAU operations. We would like to request
that you refine the following part of your query, or we may consider
extending, charging or refusing within the grounds of the Act.
“3. Mitigation and improvement efforts
Please provide:
3.1 Any mitigation plans or operational changes implemented in response to
delay trends
3.2 Any evaluations or outcomes of those mitigation efforts

Dear Lily Andrews,
Thanks for your reply. Please see my response below:
1. You specified a date range of 2019 – 2025 for this request, can we
please confirm that you aren’t after any data from this current year
(2025)? - It would be great to include the data for the current year as well. To be specific, from 01/01/2019-30/06/2025.
2. Would you like this information to include weekends and public
holidays, or only weekdays? - only weekdays will be fine.
3. You have specified a time range of 7:00am – 9:30am, are you after
information only in the morning peak or specifically between these
hours? - 7-9.30am would be fine.
4. An initial content search has been carried out with regard to the
information you’ve requested in part 3 of your request (copied below), and
has returned 4240 items. This is being assessed as a minimum of amount of

- Thank you for your response. I appreciate the scale of the task involved and understand the potential impact on your business-as-usual operations. However, I believe it is important for the public to have access to the full picture — including the issues identified, the resolutions implemented, the outcomes evaluated, and any future plans. This context is essential for transparency, accountability, and informed public understanding.
I am happy to agree to an extension of the timeframe to allow for a more manageable assessment process.
Yours sincerely,
W
