I guess I misinterpreted “bike to school day.” Oh well. I had a lovely time cycling with my kid’s bike…

Also appreciate the spacious interior bike parking area and much wider gangway. I think I’ll finally be able to bring my cargo bike on the ferry without stressing about how I’m going to get it on and off.

Finally got to ride the new Devonport hybrid-electric ferry! I kept thinking something was wrong because it was so quiet, we never got the bone rattling revving diesel engines. But the unexpected bonus was the massive windows! I couldn’t even capture the whole window in one photo. Love it!

The economic benefit to the local economy from cruise passengers is minimal, and when environmental costs are considered, their economic contribution is negative.

I was on a phone interview with a m reporter last week and they were somewhat disappointed that while I was the Tim Welch they meant to talk to, I wasn’t the Tim Welch living a much more interesting life on the South Island...yet. Hopefully, there’s room for both of us down there someday!

Apologies to @timwelch.nz that should have been @tfwelch.com for the Auckland Transport Access Atlas, which is a good opportunity for me to share this snapshot of the cycling safety lens applied to Where To Act - check it out yourself here ataa.tfwelch.com
Screenshot from the atlas that shows a bunch of dark red spots around Akld's city centre and across the centre west of the isthmus, indicating where cycling safety infra would reduce harm, based on crash data.

Never a dull moment when you‘re a public transport user! Bayswater ferry I was on seems to have run aground. They got it moving again and hustled us off the boat. Hasn‘t sunk (yet) so that’s good. But definetly a first for me!

Sometimes you see something cool, and you want it for yourself. Inspired by Anthony Castrio's nyc-cartogram, I made an Auckland version: drop a pin and the city is redrawn by public-transport travel time instead of distance, with a couple more modes and a few extra features. warp.tfwelch.com

An infuriating analysis from @tfwelch.com of how the Budget reflects transport priorities. 3/4 of new capital spending to roading, and most of that to *one road*. Zero new investment in walking and cycling. Fuel excise relief signalled, but not PT fare relief. theconversation.com/as-global-fu...

I frequently read OIA requests and responses (related to transport and infrastructure) and see all kinds of things, but this (unrelated) one made me laugh. And the genuine response is just as good. "Why did someone look at my LinkedIn?" Gotta love public records!

Budget 2026 hierarchy: roads first, rail a distant second, general public transport, walking and cycling nowhere. $150m goes to fuel supply, but basically nothing to reducing oil dependence. My latest: theconversation.com/as-global-fu...

$15b in weather losses over the past decade. Moa Point dumped 70m litres of raw sewage into Wellington Harbour. Groundwater contamination is rising. Half our rivers are unsafe to swim. Budget 2026 drops water spend from $127m (2026) → $35m (2027) → $5m/yr (2028–30). Make it make sense.

We're in the midst of the worst oil crisis in history and the government's new budget is dedicating $1.8 billion to a single highway while taking $2.5m from public transport bus decarbonisation to fund underground utility maintenance.

The percent looks small, but that’s because the base is huge. The 2.4% reduction is actually over 3 million vehicles. And, this is just trips across about 230 stable counter sites, so it could be higher and in terms of KMs travelled, likely a much bigger reduction.

Same. I think theirs is a group of policymakers that have only ever gotten around by car and unfortunately we’re (literally) paying for that now.

Tim Welch @tfwelch.com · 27/05/2026
When the government releases its budget later today and undoubtedly puts more money towards roads while putting less money into public transport and no money into cycling or walking, remember that driving is the only mode of transportation that is both currently and historically falling in Auckland.

I don’t accept that sweeping away our most vulnerable people for the comfort of those that don’t want to see our society’s inequities is legitimate policy. And neither should you. My latest piece for Newsroom: newsroom.co.nz/2026/05/25/m... #waronthepoor

You’d think a 20% rise in cycling trips from April 2025 would be headline news. 309,197 cycle trips in April, 1.30 million YTD, and 3.48 million over the past 12 months. Amid surging fuel prices, Aucklanders are finding cheaper, healthier ways to get around. More data at: cycleway.tfwelch.com

Dsta on cycling in Auckland: cycleway.tfwelch.com On crossing demand, NZTA argued cycling & walking across the bridge would be popular enoughthat the density of people on the bridge would be structurally unsafe. The Auckland Marathon has 800 people per 5 minutes, so more than that I guess.

I know. I say it, then have to explain it, then the explanation gets cut, and no one understands what I'm saying. So, I've just been going with 'the next harbour crossing."

Yeah, 2019 is a bit of an anomaly. For whatever reason, we only have a single-day traffic count for the bridge for the whole year. So, in the graph, I had to use some statistical forecasting and back-filling. The bar graph shows the one count, and the total counts are provided under each bar.

A decision on Auckland’s next Waitematā Harbour crossing is expected (maybe) next month. Worth remembering: bridge traffic still hasn’t returned to its 2018 peak, and 50% of commuters now cross the harbour by bus. So why is the current process focused on more road capacity? Move people, not cars.

Technical note: the atlas uses H3 r9 cells, OSM network routing, AT GTFS timetables, and E2SFCA accessibility modelling. That means it estimates effective access to jobs, schools, shops, health care, etc., not just nearby POIs. Built from free public data. Reproducible code coming soon.
